Cully: love the screen! Ye bastard! Just after upgrading my PC, and bought a car, so won't be getting something like that for a while yet.
As for consoles versus PC, I play Burnout on the xbox, and that's it. Battlefield series, CoD series, C&C series (will be playing RA3 again when my elbow heals), Sim City series (playing SC4000 on and off), NFS series, CS:S a bit (getting Portal & TF2 in the Orange Box for xmas), MS Flight Sim X, Crysis, etc, not to mention the applications, training videos, etc.
Upgrades are costly (around ?1000 every 3 years it seems), but I'd be bored with the consoles.
