Son and heir to family overdraft has a copy, came free as he's a computer science student and was involved in Beta test. His considered opinion is avoid for the moment and avoid permanently unless your machine is high spec (sorry, very high spec). It is very RAM and CPU heavy, he's running 2gig of RAM and notices a difference over XP.

There is also the DRM issue. His copy is now quarentined on a virtual computer with limited access to the rest of his hard-drives.

All the best
