Damm Vista
I never sell one pack of it. My customers allways ask for XP and I get more and more trouble to order systems without Vista.
Vista is slow and ugly. Lots of software makes trouble. In commercial environments you can't use it. We have a own huge software suite in development and this runs up to XP but not on Vista. The SDK what we use is not Vista ready and no new release is visible
And just changing the SDK is not possible. The whole system is to complex.
