Never buy first generation apple hardware, so many flaws with rMBP, even worse with the 13"
Can't wait to get gen 2 15"retina this fall though
I have a rMBP and it is without a doubt the best Apple machine I've ever had and I've had a lot, I've been using Apple products for well over 20 years.
The rMBP is fast, the screen is amazing and I've have never had a single issue with it. I was a bit dubious about getting it as I wasn't entirely sure, but now I have it I wouldn't swap it for anything, even after 3 months with it I still love everything about it, normally the novelty wears off after a few weeks but this machine is just outstanding.
