In theory* I'll be getting a new machine later this year. I'd planned on a 17" Mac Book Pro, but the reality is I don't travel as much, and now that I have an iPad I'd probably take it instead, so an iMac might be a better buy. I do find the lack of a matte option to be a big issue though.
* My 16 year old nephew wants to play StarCraft 2 and I told him I'd sell him my late 2008 MBP for $500. I'm not buying a new system this year if he doesn't buy it.
