All right, as I posted in another thread, I plan to make the switch soon. However, waiting for WWDC is killing me! That and I would love to get the free iPod touch from the BTS promo. To be honest, I don't know if I really need an i5 or i7 over a Core 2 Duo, or what the differences are anyway, so any advice would be awesome. These are the main things I want to be able to do: -Play a couple of games, The Sims 3 and Second Life. -Use the Adobe suite quite often (Photoshop and Illustrator mainly) with my Wacom tablet for art and graphic design work. -and possibly some light video editing in the future, but not right away, just an idea. Will the core 2 duo satisfy these needs? (And now I'm floundering over the 21.5" vs. the 27"! If I choose the 27" I feel even sillier not going with the i5 as it must be better, but it is a significant cost up from the 21.5" second model.) I guess some general info and advice would help.
