1. Assuming you’re running Windows 7, can you complete your system with free applications?

2. Building on question #1, can you run your computer — including the operating system — on 100% free software?

3. Now that Windows 7 has shot past Vista market share (in just six months), I’ll post a high-level review of what made this forgotten operating system such a sore subject for many people.

3. I got an Apple ipad for work (yes, for work).  What are my thoughts?

Rugged Laptops

One of the great things about my job is that I get to test new gear from time to time. Most of the time this usually consists of new computers that are just new iterations of existing models. On occasion, something interesting comes along. Dell has half-heartedly been in the specialty market of ruggedized computers for some time, but has recently gotten more serious with a new line of laptops. Although the market is small, it is primarily dominated by the Panasonic Toughbook line. Dell has expanded their Latitude line by releasing a semi-rugged model (Latitude ATG), a fully ruggedized model (XFR), and a rugged convertible multi-touch tablet (XT2 XFR).

While the tablet is the most interesting to me, I have my hands on the Latitude E6400 XFR. All these models fall within the Latitude line and have the same internal specs as the mainstream Latitudes. As was explained to me by my sales rep, these are Latitudes which have had the cases removed and new cases applied by hand. The ruggedization work is actually performed by a third party company called Augmentix. Building, tearing apart, and rebuilding seems inefficient to me, but what do I know? Building a rugged line on the existing Latitude platform is good news if your business already has an investment in the Latitude line. All of your images, peripherals, and docking stations should work without modification.

What is a Rugged Laptop?

The term “fully ruggedized” is confusing to some. The term does not imply 100% waterproof. The computer is meant to withstand dirty conditions, moisture and rain, salty fog, and some abuse but cannot be fully submerged.  Update:  My Dell rep told me today that the XFR can be fully submerged in the case of a drop but should be immediately retrieved. There are no exposed ports, the speakers are enclosed, even the heat vents, speakers, and webcam are covered. The XFR achieves an ingress rating against blowing dust and moisture of IP65 (if you know what that is).  To further clarify what rugged means, there is a battery of military spec tests. The results are impressive.

To further increase the durability, my eval arrived with a solid state diskdrive(SSD) to reduce the chance of mechanical failure. Dell utilizes an alloy casing called Ballistic Armor Protection System featuring PR481 which they claim has twice the impact resistance of traditional magnesium alloy. (I’m assuming this Ballistic Armor is a marketing term made up by Augmentix.) I have performed some minor drop tests but can’t bring myself to really test the durability. Dell claims the XFR is first in class to achieve the military’s MIL-STD-810F specification for a four foot drop on plywood over concrete. My test was a two foot drop on carpet over padding as I prayed.

You would think with all the covered ports, that heat would be a concern. According to Dell, the XFR meets military standard MIL-STD for temperature extremes. Heat dissipation is managed by their QuadCool thermal management system (See photos below for the QuadCool vent).

XFR Performance

The computer does not lack horsepower. This is one of the most responsive computers I have used in the business laptop class. I am running Windows 7 Ultimate 32-bit and it takes about 20 seconds from power-on to being in a usable state. Impressive. There does seem to be a refresh glitch with the Intel video driver from the Intel site.  I find myself having to minimize/restore various windows to force a refresh. There is also an Nvidia video option which probably does not suffer the same issues. (Update: I used Intel’s Auto Detect utility on http://www.intel.com/support/detect.htm and installed the latest video drivers. Refresh problem solved. This proves you should always update your drivers.)

I should note that this is not a Dell image with the typical bloat/crapware.  I installed Win 7 fresh from the installation DVD and added drivers from the Dell support site.  To further increase responsiveness, I am using Microsoft’s Security Essentials anti malware program and not a resource hogging program like Norton or McAfee.

Other XFR Observations

As I mentioned before all the ports are covered to prevent dust and moisture from entering the system. The port covers are opened by a two step motion by pressing and sliding the release.  These doors feel a bit awkward compared to the Panasonic Toughbook doors. The SD card slot is the most inaccessible. It is located behind the handle on the front of the unit.  Open the cover and inserting the SD card involves some phalange gymnastics. Even getting a good photo (see the gallery below) of the SD slot was difficult. Other than that, the design seems well thought out. This model includes a VGA, Display port, modem, Ethernet, three USB, one USB/eSATA combo, PCMCIA, SD slot, fingerprint sensor, and one 1394 Firewire port. Like all other manufacturers, there is a swift move from serial interfaces. This laptop is no exception. The serial port is following the steps of the parallel port and the diskette drive.

The battery is small and based on the body design, I don’t think an extended capacity battery will fit. (Although there is a “battery slice” option available for extended power.) With Windows 7’s power management features, and the SSD, battery life has been very impressive so far.

An important note is that Dell will not release an 6410 XFR.  They are sticking with the 6400 and will most likely release an update with the 6420 product refresh.  Interestingly, there is a 6410 ATG.

Dell XFR Accessories & Serial Port Adapter

There are NUMEROUS accessories available for the XFR.  There is a shoulder strap that screws in brass screws near the built-in handle.  There is a “battery slice” which is a flat extra large capacity battery that screws onto the bottom of the laptop.  To solve the lack legacy ports, there are two legacy port extenders which attach onto the bottom of the unit with metal screws. There is an adapter with one serial (RS-232) and one parallel port, and the other comes with two serials. These serial adapters are big and rugged, but they secure to the bottom of the unit very tightly.

UL Certification

The Latitude E6400 XFR is UL1604 Class 1 / Div 2 certified, but the ATG is not.  I believe you can get the Panasonic certified also, but only in a touchscreen unit. Keep in mind that these devices are only certified when all port enclosures are closed and locked. The Latitude ATG is not certified at all and no device that I have found is Class 1 / Div 1.

Dell XFR vs Panasonic Toughbook

This note is not a Dell vs Panasonic comparison. However, it’s hard to not make some cursory observations. Compared to the Panasonic Toughbook (CF-30 & CF-31) the XFR is a modern device.  While Panasonic invented this niche, the Toughbooks have stuck to their original design and compared to today’s standards seem bulky and ugly. For example, even though the CF-31 is new, it still has a 4:3 aspect ration, while the Dell has a modern 16:9 screen.  Panasonic claims they are sticking with the original form so that existing users can leverage their docks and truck mounts.

Furthermore, Panasonic’s driver update model is odd. First of all, you need to register to download updates. Then, since they don’t update model numbers often, you need to know what “mark” your Toughbook is (roughly equivalent to the date it was produced).  Then, once you get logged in, you download driver updates in packages.  On the other hand, Dell treats driver updates like they would any other Latitude. You simply browse to support.dell.com, select your model, and download the driver you need.  Much simpler.

Dell Latitude XFR Photos

Here are some photos of the XFR. Sorry for the lack of professionalism, my wife sold her studio a few years ago so all I have now is my dining table.

Additionally, the guest OS (XP in this case) runs on a virtual hard disk (VHD).  The VHD is actually a large, single file on your physical disk.  To the host system this is a single file, but to the guest OS, this looks like a physical disk.  From the host you can move this file around, back it up, delete it, etc… Keep in mind that if you delete this file, you are essentially deleting your guest operating system.

To get started, you need a virtualization engine such as Microsoft Virtual PC (also free).  Once VPC is installed, you need to download XP Mode (this is a large download since it is a full copy of XP SP3).  The setup is painless. The only info you will need to provide is an admin password for your XP instance. Obviously, you can customize all kinds of settings but the defaults are acceptable for running XP. If needed, you can go back later and adjust memory, disk size, etc.

Once the setup is complete you can do anything within the virtual instance of XP as you would do in any other OS. You can install applications, surf the web, change the wallpaper, etc…

In this image you can clearly see XP with IE6 running within Windows 7

So why would you want to run Windows within Windows? I can think of several scenarios in which you would need to run XP within Win7.

1. Keep in mind that Microsoft’s biggest competition for Windows 7 isn’t Linux or Mac OSX, it is XP itself.  Windows XP is everywhere in corporate America. Applications have been written to run on XP since 2001. Many of these apps will indeed run in Windows 7 but there are many that will not.  In a perfect world, the developers would go back and update the apps and provide free upgrades, but Microsoft realizes this isn’t going to happen. So, in order to hurdle the compatibility barrier, they decided to basically give corporations the ability to run the apps in XP within Windows 7.  Not exactly efficient, but a solution exists.
2. No matter how successful Windows 7 is, there will still be people running XP for years to come. Unfortunately, many of these people still run Internet Explorer 6. Web and app developers need a method to test their sites on this older technology. Instead of keeping an old PC around just to test their site on IE6, they can simply fire up XP Mode with IE6.
3. Since the guest OS is installed on its own virtual disk, you can use the virtual instance as a security sandbox for anything you wouldn’t want to do in your host system.  If something gets hosed, just delete the virtual disk and reinstall XP Mode.

Running XP in a virtualized environment is not new or groundbreaking. So what makes XP Mode different?  For one, you actually get a free licensed copy of XP (most virtualized copies of XP are boot-legged).  Secondly, unlike some virtualization engines, the experience is seamless. You can easily copy/paste between the host and guest systems and there is a single mouse which traverses all instances without synchronization. Next, and really cool, is the ability to add a shortcut to a virtualized application within XP to your Windows 7 start menu.  This is significant because it hides the XP OS and only exposes the application to the user.  This is referred to as publishing an application in XP Mode and is enabled by putting the application in the ”All Users” group in the virtualized XP start menu.

In this screenshot, you can see a link to Google Chrome which is installed in the XP virtual instance. Chrome is not installed on Windows 7 in this example.

..and here is Chrome running in XP Mode without XP being visible.  Keep in mind Chrome is really running in a virtualized instance of XP.
