I'm with you on this one. It's very easy to step in, say "Apple sucks" and then back out without giving any relevant reasoning. The post said cheap motherboard, cheap memory. It's all custom, you can't go to a Micro-center and buy this off the rack, how do you know it's cheap?
And yeah, if you're going to comment that Apple isn't high quality, you do have to give an example of one that is. Lenovo? Microsoft? Those are good comparisons I guess, but I don't think anyone would put the two next to each other and say Apple is a lower quality.
