re: MBP overpriced
That's not really a great example, though, because Mac RAM upgrades are overpriced like that across their entire product line. They like to charge big markups on larger capacity hard drives too, whether you're buying for a Mac Pro, an iMac or a Macbook Pro.
Honestly, I've always thought the Macbook Pro is one of their systems that's difficult to price-shop against other notebooks. (EG. If you believe PC Magazine, the current MBP outperforms practically every other notebook they ever tested in running Windows Vista. Technically, it's been pointed out that "fastest Windows laptop ever" is a lie, because they once tested a "gaming laptop" that was faster. Only thing is, that laptop was around $4,000.)
How much of a "price premium" should there be for a notebook that performs so well? How much for the fact it has an all aluminum case, backlit keyboard, or superior "mag-safe" AC adapter design? Don't forget it has an iSight camera built-in too (typically something not included in other notebooks on the market).
I think the best argument for the MBP being "overpriced" is comparing it to the regular Macbook. Then you're at least comparing two machines that both include and legally run OS X, both with mag-safe adapters and integrated cameras. But really, if it wasn't for Apple coming out with the last couple revisions of Macbooks - I'm not so sure the MBP would look "overpriced' at all?
I just noticed apple wants $700 US dollars to upgrade to 4 gigs of RAM, 2x2 where you can get the same memory for <100 and install it yourself.
Good testiment as to how overpriced the MBP line currently is.
