We have been playing with it from earliest betas, mostly to look at security functionality, but our conclusion throughout is Baaaaad!

Security-wise I am likely to advise most of my clients to stick with up-to-date XP if they have to use Microsoft, as the 'wonderful' security features MS brought in will actually leave users far less secure.

And from a performance perspective it is just a pig. There is almost nothing it does thatI can't already have under linux or MacOs - and they do it far more elegantly and with less overhead. Same old story I think.

The upside is more and more organisations are becoming hacked off at the whole tie-in thing and are leaving for more open platforms, especially my government clients, so that has to be a good thing!
