Actually, that's a good point : I don't know of ANY businesses running Vista and the company I work for has no plans to upgrade from XP anytime soon (we run what our customers run, hell we're still on SQLServer2000).

EDIT: to clarify when I say 'I don't know any businesses running Vista', I should have put 'I don't have any customers running Vista, or have any friends working at companies running Vista'
I agree with Dr Herbie I dont know of any businesses running vista either.
