Out of personal curiosity and as someone who gets involved with SME's from time to time I was wondering how many UK SME's are considering moving to Vista and what is stopping them from doing so at the moment. Also what time scales they are looking at to move over to it. 

As a developer I'm wondering at what point we need to start considering re-testing our released softwares for Vista and the people that seem to be closest to moving over seem to me to be the SME's as they generally seem to adopt new technologies earlier

So who (company wise) is considering it, who's done it and who's just not going to bother in the UK?
