Hey guys. Im just on the borderline of joining the MacBook Air family, and I currently have two options; A 11" 2011 brand new MBA from the Apple store (with student discount, so £750+£65 gift voucher), or... A 13" 2010 used MBA (£700). The 2010 is the 256GB configuration, while the 2011 MBA is the base model. So basically, the difference is; -11" vs 13" screen -Battery life; 5 hours vs 7 hours (although the used 13" I would expect has worn down a little) -i5 1.5 GHz vs C2D 1.86GHz (Obviously the new 2011 wins, but how much is the difference?) -Backlight vs non backlight (although this isnt really a big deal if you ask me) -Memory; 64 GB is actually plenty for me, but I guess extra isnt a bad thing. -Warranty; the 2011 MBA will the years warranty, while the 2010 has none; is this a major issue? -£50 more for the 2011 11" What do you guys think is the best deal? I really cant make up my mind, and struggling to decide. I think the 13" screen would be nicer, but is the difference in processor extremely noticeable? Is the C2D really out of date now? Thanks for any opinions!
