Query: Buyer beware.

Do not buy a used iPAQ Pocket PC or anyother Pocket PC. I bought one for my wife for Christmas(I will be paying for this for a long time). Received it before the 25th. We just got around to trying to down-load the software to my laptop. Well it seems that we need a 25 character pin code to do anything with the PC. It did not come with the code and HP wants to charge $50 to try and help to get the PC to Hot Sync with the laptop. Plus they don't even support it anymore. Right now I have a $179 useless piece of hardware. Again, DO NOT buy used or refurbished unless you can verify that all the information is there. PS: The seller will not take it back.
