Pretty.
I have to stick to laptops for the mobility because I'm a travelling student. Anything with a decent graphics-card, quad-cores and 64-bit OSes (and the extra RAM they afford) would make my day.
Right now I use a VPN to dial my brother's PC in another country for the heavy rendery-stuff, but I still need a workstation-ish PC to work on the models in the first place. XD
