A friend of mine got hold of a beta copy of Longhorn (now Vista, but I believe its the name for the WinServer2003 upgrade now) and said that while it looked good, he can't see a great deal of difference in the actual running of the system.

To be honest I can't imagine ANY OS taking up 800MB of RAM, but if Vista does then I can see a lot of people sticking with XP. Having to upgrade your system just to run the OS is crazy.

I, however, am building a new PC that will have 4GB of RAM, along with 800GB of HDD space and so might look into geting a copy of the Vista beta to put on it, before I install all my trusty, old programs (inc XP) and if I can and do get a copy, I will test it and put up the details along with some screen shots for you all to look through.
