Hey, I am brand new here but I just wanted to point out that tyrannozaurus.com has an SD card compatibility list. Anyone who is looking to buy a card can look there for other people's experiences. Also, anyone who has cards, particularly 4gb ones, should add to the table. SD cards are one of the most difficult things to buy for the Zaurus since 4gb non-SDHC cards are not really a proper standard. Thanks, and great board here.
