Re: Well if it can support standards then it is aleady ahead of the game
MS and Exchange is all about lockin to expensive licenses and support contracts. It is not about features that users may find useful.
Moving from say Apple to Android (or the other way round) is easy just time consuming.
Moving away from Exchange is a major undertaking and certainly one that you don't do on a wet afternoon.
Personally, I find Exchange/Lookout in the Orifice 365 incantation to be just about usable and that is it.
With a totally locked down desktop where I can't change the way Lookout shows email chains it frustrates the hell out of me.
My takeoff to a MS free life is at 3 days and counting. Can't wait for friday afternoon then I'll have a few beers.
