Query: Rip off

Three words: "No" "Power" "Supply" :( You've got to pay $20 more for a power supply. That, and they don't even offer an automobile charger (if you don't use theirs you might void your warrantee). Compare this to a Compaq and it is obvious which is the better product. Take it from me; buy a Compaq iPaq.
