One of the drivers pushing me towards a rMBP is the overall build quality and customer support. We have a couple of iPads and an iPhone and really like the quality. I've always been a Win PC user, and my last two Win PC's have had motherboard issues at the 3 year mark, which is frustrating to say the least; both were better grade consumer PC's in the $1,000- $1,200K range. So, before I spend $2.5K on a rMBP, are they really better made, and do they really outlast comparably priced Win PC's? Please don't misconstrue, I'm, not looking for a Apple vs Windows PC war; I'm only seeking constructive comments from folks who have some good background experience. Thank you guys again!
