One of the advantages that Linux has over Windows is the ability to run on very old hardware and still not be crippled. For example, you really need a computer made in the past few years to run Windows XP comfortably. This standard has forced people with perfectly fine computers to dump their old ones and get brand new ones. On the other hand, current Linux distros, can be modified so that it is able to work on lower end systems. While you may not be running the latest KDE, you would still have access to all the newer features of drivers and hardware and even the latest software if you run a stripped down (but not necessarily ugly or unusable) window manager (Fluxbox comes to mind).
Knowing this, it has taken Microsoft a long while to do something about it. Now, they’re finally attempting to reach those they’ve abandoned and are still using Windows 95 or 98 because they don’t want to waste money and perfectly usable hardware.
I question their decision to use the memory hungry Windows XP look and feel for these computers. I would’ve assumed that taking out useless eye candy would be the way to go. It’s not like those huge title bars are helping anyone working in 800 x 600.
