I'd sign-up if I wasn't an MSDN user... bit pointless to me atm.

i would sign up
 
but it is likely the cd would never make to me in Antigua.

I've downloaded it from the MSDN site. I haven't had much time to play with it, but so far I'm impressed. It actually looks like a server OS. The first thing I noticed was the missing GAMES shortcut on the Start Menu. No more brainless admins playing minesweeper on the Domain Controller.
 
I ran through the Manage My Server wizard and was surprised at how well it worked. A shaved monkey could set up this server. I want to play around with SUS since it comes as part of .NET server. I'll be able to see what kind of resources it uses up so I can determine if I want to run it at work. I don't know what to think about activation having made it into Microsoft's server OSes. Doesn't really phase me much, though.
 
In all, .NET Server looks like a fun new toy.

I signed up a couple of days ago. Maybe I'll get an email from them in the next 2 weeks!
