Seriously - what Littlebluething said. Just don't go the vista route - most of my multinational clients (who admittedly have been slow to move off NT!) are in a position now to go down the linux route over the next 4 years - and considering they are all 100,000+ seats, this is going to soooo pi$$ off M$ and make their IT teams soooo happy:-)
Ahhhh - the bliss of a securable yet functional operating system (M$ can be both of these, only not at the same time!)
(all of the above, my not so humble opinion - not my employer's)
