I've run Vista 32 and 64 bit on two seperate machines with no problems (that I haven't caused myself)
I read that recently and was a bit surprised. I don't see it as a negative except for people who don't know how or where to find the apps they might need. But that's what "geek" friends and neighbors are for right?
I played around with a cool math/calculator app on Win7 that I hope stays (called Math Input Pad or Panel or something like that). It looked like a notepad you could "hand-write" math equations on and it would solve them. Quite cool.
