I have a 15" rMBP I bought back in June. It's experiencing pretty bad image retention. I'm not being picky, I've tried to just disregard it for a few months because I didn't want to send it in for repair. But it seems to have gotten progressively worse. If I leave Skype open for 5 minutes for example then switch to full screen Safari, the outline of the window and text remains. My question is, have any of you had them repaired? What's the turn around time usually from day shipped off until day recieved? I use my laptop a lot and want to get it fixed befor spring semester starts. I don't live near any Apple stores.
