Keep in mind that you'd need
to buy an external Flash card to get close to the storage capacity of the iPod Touch.
I know Compact Flash cards at 8 GB are readily accessible now, and at the outer limit I think I've heard of capacities up to 64 GB if you're willing to pay through the teeth for it.
SD and MMC cards are available at up to 4 GB right now. I think they've been announced in capacities of up to 8 or 16 GB, but I don't think they're available yet.
