Places like Amazon now offer last weeks base 15" MBP for $200 under list - and no tax in most states. I picked up my 2010 15" MBP on Black Friday at Amazon and if they have a big sale like last year I may pick up the 'new' base 2011 model and sell my 2010. Yeah, I lose some money but I also get a 1 year warranty, 2x bigger graphics CPU and a quad core for my photoshop work, plus I still haven't moved over to Lion so maybe I will update. Aside from Photoshop and Aperture work the performance difference would not be realized.
