Sorry, don't use the thingy thing, but do have Vista.
To be fair, when XP came out people said there were going to be so many issues... there really weren't that many notable ones
The only thing I have come across thats an issue is can't use my old creative webcam (no biggy) and firefox crashed twice in 6 months.
If people say that it takes up too much memory, it is DEFINATELY more economic with the memory and it is not noticeable.(my system is bordering minimum requirements)
so basically, If you want Vista for general usagage I would recomend it, If you find an issue with compatability, either :
Dual boot the system so you have both or
or have a looksy at VM Ware, so you can then run XP as well
and Vista is damn pretty :D
