Hi Dave,I can ask at work for you and report back, though I must admit that "big business" wouldn't advocate a migration to new Operating Systems, etc without years of trials first! (We're still using Win'98 & Win'NT v 4)
Like you I an an IT Consultant, but my speciality is in IC Cards, embedded systems and formal specifications.
Strikes me that there could be an element of "The cobbler's children are the poorest shod" here!
