Couldn't wait, I just spent $3k on a new MBP...
My older MBP is dead, I tried to wait out for the new update but wasn't possible any longer :/
Has anyone tried returning a MBP to Apple Store every 14 days until the new one is out? Is there a limit to how many times I can buy and return MBPs?
In the last couple of months I have 'borrowed' a rMB, an Apple Watch and a 13" MPB. Considering buying the 15" to test that out too. Had no trouble returning them so far.
As an added anecdote, I saw some guy in an iPad forum who said his friend (not the greatest looking source I know) who trialled 5/6 iPads in a row before he got bored of making the trip to the Apple Store to maintain it.
Edit: if you really want to push it, there is a way to get them for up to 28 days at a time. At least in the U.K., the T&Cs state you have 14 days from the day you physically come into possession of the product to let Apple know you want to return it. You then have 14 more days from the day you've told them to actually take it back.
