I do expect it will be back with Apple again when it deteriorates further, and after the previous hassles this is not something I look forward to but am prepared to pursue the problem to the end of the next two years.
Good luck with your AlBook. Alas my patience is not as good as yours. The thought of having to continually send this in for repairs is just not for me. I simply do not have, and cannot afford, the time to 'nurse' the thing all the time. My rule is that all my Macs have to pay their way, or they're out. The problem will be what to replace it with.
I never thought I'd ever say this about any Mac, but sadly this AlBook will be on its way out the moment I get an acceptable offer from anyone else prepared to put up with its unreliability.
