Interesting that they can predict they'll charge $179 for something 5 years from now - won't the technology be better, more refined and less costly or are they buying a sh*tload of batteries now expecting to need them in 5 years?
That's a valid, and yet mute point: wouldn't a hard drive die out in less than five years (more like 3-4)? It's hard for me to imagine someone using a laptop for more than 5 years - especially someone who cares enough to buy the top-of-the-line version (most likely a power user or designer of some sort).
