CF flash is different
Also, keep in mind that the flash chips used in CF cards are different from the type of flash chips that are in the Palm units.
CF cards use serial access flash. You have access it serially - you can't just hop to an address in flash and read out one byte. This makes the chips less costly.
Palm PDAs use full parallel access flash chips. These cost more.
This is why the Handspring Backup Module costs $40 (serial access) and the Handspring Flash Moddule costs $80 (parallel access), even though they both have 8MB of flash in them.
Also the cheap 2MB and 4MB CF cards are flooding the market because people are either selling their old cards because they bought new 32MB cards, and because no one really wants such a small amount of memory when you can get 32MB and 64MB cards that store many more photos and much more MP3 music. Small demand and large supply = low cost.
