The swap partion is the one reason i wont abandon microdrives, at leat until they put some decent memorey on PDA's (looks like 128MB is starting to become standard)
you could however make a CF card out of RAM but it wouldnt have any where near the speed of native ram, hmm perhaps this is somthing i should add to the hacks page, how to use your old SDRAM sticks with your c3000?
ether way the next big thing for flash seems to be putting FLASH SDRAM and SRAM in the same package but phisycally stacked on top of each other, you can get an xscale chip like that with 32MB of RAM and FLASH on chip
