I am considering upgrading from my 13" late 08 unibody macbook to a 27" 2012 iMac and take advantage of Best Buys current sale combined with student discount. As a premier silver member, i get a 45 days return policy so even if they went on sale more, i could return or get price adjustment. My only hesitation is if I will enjoy going from have the portability to not. My first mac was a imac and then I bought my current macbook. Though now we have iphones and iPads vs when i first had my imac so portability prolly wont be as big of a factor. Anybody else struggle with that?
