I'm going to be reciving a Sharp Zaurus SL-C3000 soon. This system is already linux based and has a Intel XScale PXA270 CPU at 416 MHz, 64mb of ram, a 4gb harddrive, 16mb of flash for the kernel/bootloader, and a fill qwerty keyboard. This system is perfect for development. We could get a lot of bugs out of the way using a chroot build or a boot build instead of trying to cross-compile the whole system like you would be forced to do with almost all of the other PDA/Embdedded arm systems. I would like to add arm to the book. Thoughts?
