Hi, I've been a windows user since I was a kid, probably 15-20 years now. It has worked for me, but since I got an iPhone I've never wanted to switch back to any other phone. I get the impression that it's the same with a mac computer. So now I really want the 15" rMBP. I've probably googled the entire internet for threads about it, and the issue with image retention/ghosting scares me. If I'm going to pay over 3000 dollars (that's what the lowest settings cost in europe, FML) I really want something flawless. And I'd hate that my first mac-experience was ruined by the notebook not being as great as it could be. So, what do you say? Should I just go for it? Do you think I'll be disappointed? Or is it unwise to buy a first gen retina macbook now, so I should wait until next gen 2013?
