Screaming Penguin - Source Does Matter

Very odd... my experience was much better. The MacBook Air was repaired in one day. Reported it on a Tuesday, dropped it off on a Weds when the LogicBoard came in, and then picked it up Thursday (the tracking on the Apple site actually had the repair complete early Thurs morning).

I guess it depends on which Genius Bar you go too and if the Genius' there are actually technically savvy. In all the Apple Stores I've been to in the NY/NJ area, the geniuses have always known what they were talking about, down to the "checking console logs, open up and replace motherboards, diagnosing wrong Objective C code level." Of course not all that knowledge was rolled up into the same person... but at least each of the geniuses I've spoken to had that level of expertise. So far I haven't needed to have my Mac's sent away for anything. They've always stayed with me until parts came in for the Geniuses to repair in the back of the stores.
