I wanted to test a new 4gb card I bought and I transferred 2 albums over using USB... it took six minutes maybe... Then I popped the card in an adapter, slapped it in my laptop and transferred about 40 albums in under 7 minutes. Not blazing fast by any means, but USB can get stuffed... I'm using the adapter.
I concur that it's a bit of a drag to pull the battery each time I need to access the card. I try to see the bright side, though... I pull the battery from time to time anyway. I just try to sync my data transfers with my battery pulls
