Am partly disagree, that an Amiga (like/based/etc.) palm is a bad thing. Stuffing an A500 category machine into a palm size today is not that impossible task as it may seem.
Remember it had 512K memory (1Mb with expansion), while my Palm505 has 8Mb. (And 510 16Mb, and it just increases) It had a much slower CPU than which is in my Palm505 too, and the dragonball is pretty much compatible. Custom chips may be problematic, but the idea of having programs and an OS with the footprint of A500 programs and OS3.1 in a palm sound pretty realistic, methinks. I'd definitely buy one.
