I've found my HP iPAQ 1910 very useful. As well as the usual PDA functions it's got my song list (with the words), my LP and CDs databases, serves as an MP3 player, carries several books using Microsoft Reader, and will soon serve to bore you rigid with photos of Thailand!

On the minus side the battery life is a bit limited away from home (but I imagine a car adapter would be good - you can't get one for a pushbike), and there's no ABC player yet that I know of.
