I've just bought an iPad (my luck, bought it before finding out about version 2 release) and as far as I'm aware the transfer of files between a PC and one are very limited if impossible. I can't or haven't found out, for instance, how to transfer eBooks bought through iBooks to my PC. As far as I can determine you can only transfer application data that is compatible with FileSharing on the iPad and only through iTunes. Although if I'm wrong someone is sure to correct me.
Thanks for the answer, I want to transfer mainly data files, MS Word etc, also Photos.I just noticed that there is no USB port. I would also need to do my banking on it, is it secure? I have never owned an Apple so I know very little about the system.
Not sure of word files but pictures can be transferred through iTunes, there's a tab in the iPad section for synching them to a folder on the PC.
Banking security would be determined by your bank, my bank security only works with Internet Explorer for instance. I myself would stick with the banking method you use now. A lack of AdobeFlash may limit banking with the iPad, I would check with your bank before hand.
