MS is touting that Win 7 capable is about that of Vista — however some features such as Win 7 VM or ‘XP Mode’ may not work depending on your processor and BIOS

I wonder hoe many systems will go out with a nice little stamp stating Win 7 capable — that will not run some features?

But then again, I guess you get what you pay for. Also to note — this is not really for most people anyway — BUT — for those who may want it, it is something to look at.
