Got to agree with Capt Horatio...
If a PPC is what you're going for, the Axim is a great device. Reports of it being "chunky" aren't false, but it is no chunkier than an iPAQ. I should know - I had an iPAQ until it got run over in Denver
I also have a wireless CF card for the Axim, which works well and store music on an SD RAM card that slots in the side.
Jubbly.
