Asus has recently been contracted to make Apple laptops and have done so already, making the asus PC laptop shells equivalent in hardware to a mac, with 3 year warranty on the shell and all parts you need for it (RAM, HD, CPU) with a 3 year warranty if you buy them retail) for much less.

Asus is consistently one of the best hardware companies around for motherboards and the like. They also have AMD64 shells available, another option macs don't have. You have to build it yourself or get a internet or local cpu store to build it, but this is news for nerds, right?
