I'm entering college this fall, parents want to know why I want to spend $1200 on a MBP when there are laptops going for $500-$800. I told them 7 hour battery, no viruses, the iPhoto/iLife software, and most importantly, it's reliable. But I just said reliable because I've read that many times. What really makes it reliable? I mentioned to them that practically every PC we've had eventually slows down tremendously in the long run, with my current laptop having gone through 2 crashes. Oddly enough, they think I should keep this 3 year old laptop which gets less than 2 hour battery and is highly unstable for my first year, but how else do you convince someone (who doesn't necessarily have a good background in technology) that a MBP is worth the extra $500?
