Desperately seeking arrow keys on the virtual keyboards - it is nearly impossible to type without them. I don't need two shift keys or two of the .?123 keys and the spacebar could be made a bit smaller to accomodate left right up down arrows.
Real file management on the iPad rather than having to use iTunes which is a drag. I don't mind having the operating system and major system working files hidden, but give me access to control data files for my apps, and to hook via USB to my laptop and copy move delete rename files on the iPad for all my apps as well.
Being a PC user and new to the iPad, I was stunned at how many of my favorite sites don't function properly due to the lack of Flash player. Apple has been claiming Flash isn't necessary since HTML5 will take over - well it hasn't. My fantastic new device seems hampered! My favorite Spanish language site is strictly Flash and I am upset I cannot use it on the iPad.
Other than that pretty much a satisfied customer.
