The reason I upgraded was I was building a new machine and needed a new OS license anyhow. So why buy XP when it's EOL soon... Vista Ultimate cost me 45$ (Microsoft store 4tw), runs everything I use just fine. Much improved 64 bit support from what I understand... the only app I've tried so far that doesn't work correctly is iTunes (won't rip/burn CDs or sync to iPod/iPhone - but that's actually a 64 bit thing and not a Vista thing). It's actually MORE stable than XP, the only time I've had it crash is when I had swapped some RAM and had the timings wrong.

I really think Vista just has a stigma about it, just like every other time MS comes out with a new OS or version of Office or what have you, it's always the same "oh god don't upgrade it's horrible" yet in 2-3 years everyone is using it even though the service packs really don't fix much.
