I purchased my RMBP in June 2012. I have used it everyday. My only breakdown so far has been the power cord. I purchased an after market power cord that lasted 6 months. I went to the Apple store last year and purchased a new Apple power cord. So far it has worked well, as has the RMBP. The battery still works, although doesn't keep a charge as long as it did when it was new. I would say it is 70% of what it was when new. I believe this is the best notebook computer I have ever owned. I have had at least 9 notebooks. I have been using computers since 1987. Before I started to use Macs I built my own computers, and enjoyed upgrading my desktops and notebooks. The non-upgradability of the RMBP has not bothered me in the least. I maxed out the memory and the SSD when I purchased it. I did not purchase the Apple Care. Still using my RMBP everyday. Although I plan on upgrading to the next RMBP that is released by Apple.
