2.6GHz vs 2.7GHZ... i dont see too much of a difference to justify $250 8GB vs 16GB... a no brainer as upgrading is impossible after, id go with the 16G 512GB Flash Storage vs 768GB Flash Storage.... idk if its worth the $500. how important is the flash storage? is it necessary. will i regret not opting for it? are there alternatives. USB SuperDrive... at this point i am highly considering it as i have software that require an optical drive to be installed to the computer.... ThunderBolt Display... while it would be nice, that pricetag is killing me. yes, i am a graphic artist and animator and a big screen would be nice, however i think i can do fine without a big screen until i upgrade to the 2012/13 imac... if it ever comes out.... :/ AppleCare... another given... i have horrible luck with machines... i cant afford to have something so expensive break on me... So what is everybody's preference when it comes to how to order these? what is necessary and what is not? i will be using it for graphic design, 2d flash animations and hopefully creating flash games with actionscript 3.0, and hope to get into creating game apps for ipod/ipad/iphone.
