the computer that lasted me the longest was the one I built myself. Funny how when you don't have tech support, you are forced to learn how to do things yourself.
As for the argument going on here, it's basically the age old mac vs. pc thing we've heard a thousand times before. Yes, apple is overpriced for the hardware you get. The design is outstanding, but it alone does not justify the price. Most mac USERS agree that the combination of design, hardware stability, great OS, unification of components, durability, customer support, etc, is what makes paying the apple premium. Most apple FANBOYS will defend their macs to the death, and unabashedly call windows users stupid, wrong, poor, etc. This is why the majority of PC users (aka, the world) hate Apple users, because it only takes hearing a few fanboy rants to make a lasting impression.
In reality, they're both just computers. Both have their strengths and weaknesses, both get the same job done, both can make you perfectly happy. Apple is just more expensive (for a variety of reasons). I'm sure a good part of the apple tax fuels their marketing department, which is the reason they're so desirable in the first place.
