Capita generally stay quiet on these issues, only appearing to correct incorrect assumptions and mistakes said by others. As I'm basing all my comments on numbers that are sourced to the Becta, and their own accounts, along with my own opinion, then there isn't much they can say to argue back (well, not without annoying me even more).
I know a number of companies going Vista because Windows 7 isn't mature, even though they are going to be stuck with it for many, many years.
I stick by my statement of Capita needs more people or at least open source some of it (yes, lets start that argument!)
PS: Wonder why Capita is keeping quiet ;)
