Title: Q: Why so much more than the CF sleeve? A: a battery
Review: In case you're wondering, the PCMCIA (PC Card) expansion pack costs more because it's got its own rechargeble battery (PC Cards need more juice than CF cards). I assume it recharges from the cradle along with the iPaq. It's bigger the the CF sleeve, of course, but if you want to be the first on your block with proper wireless web access (none of the Palm web clippings nonsense), you'll have to take the PC Card expansion route.
