I'm trying to decide if I should buy a MBP or not, I do have a 2011 iMac aswell as the new iPad. Anybody that has both a MacBook + iPad, which do you use more? Also if I buy a MBP it will probably be a late 2011 13". I might buy refurbished from Apple to save some cash. Is the RAM setup just like the iMac? 2x2 2gigs with 2 open slots? Or is there just 2x2 2 gig? Because if I get it, I'll be upgrading the RAM. Thanks for any help!
