Guys. Seriously. Shut up for a sec and listen to something I like to call being unbiased. It's great. Also, please read the whole post. ;)
Macs do have a superior build to most other laptops (and many desktops) out there. I know this not simply from observation, but again from experience. I have an Acer that is several years, but way more broken than a computer should be (and not because it was mistreated). I have a friend who has a 17" ASUS, but despite the laptop's power, it feels like it'd be utterly destroyed if you dropped it a foot. I have a friend who bought a MacBook Pro and immediately installed Windows on it. Why would he do that when he could just get a computer with the same power for much less? Because it offered superior build quality compared to computers with similar power and features. There's something unique to Macs; these days, their casing is all billet aluminum. This aids in two things: cooling and durability.
Cooling: Most people don't realize this, but the casing on Macs offers excellent cooling, which, in turn, increases performance and causes the internals to last as long as they do - although I'm not saying another brand couldn't last just as long.
Durability: Pretty simple, this one. I have personally witnessed three Mac laptops falling onto concrete floors (from at least three feet or higher) without a scratch - and that's with one falling directly onto the corner of its screen.
Now, remember, I did say unbiased. As a result, I would like to make it clear that there are some super-strong Windows-based laptops out there that can give a MacBook a run for its money. I believe Lenovo makes some, and there is also a computer called a ToughBook (my friend who bought the MacBook also has one) that can stop bullets and get run over by a car. In fact, my friend has had 100+lbs of steel pipes fall directly onto his. However, both are still expensive options.
So please, people, just understand something before you go off spouting about it.
