Its a developing trend, I met someone over the summer who had a slightly modded AlBook and I started talking to them about it, turned out he was buying these systems new with developer discount, modding them, using them for a few months then selling them on eBay for more than then he was getting them for. I'm not a fan of the idea but its happening more and more, Computer Shopper did a feature on modding a couple months ago and Popular Science has been sticking a hardware hack or mod into every issue for a few months now. Even off of eBay there are any number of ways to make money as a modder.
