@gmpix I had an issue with a MacBook pro - 5 (free) motherboard replacements later they replaced the Macbook for me. I had paid extra for the 3 year warranty if I remember rightly. It was a pain at the time, but it was replaced with a better machine 1TB SSD which was the nearest to my 750GB HD plus everything else equal or better. There was a recall on that model then, even for ones out of warranty, so if there's a gotcha you might be okay. It has kept going faultlessly now for 5 years, but I do use it on a tray with a fan when I'm processing photos to keep it cooler.
@Hanley keep us updated. I have just bought a grey R5 and love it so far.
