Vista is stable
All W7 is is Vista with a few front end bits changed, they haven't rewritten the core engine.
One problem many users will not be aware of is two things:
You can't upgrade from XP as you would think, you have to as good as install a fresh W7 and reinstall all your software.
Most of the programs you may use in all versions of windows are not now installed to conform with worldwide monopoly rulings, so you have to download them from MS, but as the EU version has no IE installed!!!
I don't remember Apple being forced to take out software from its OS!
