One of the problems I have with calling the iPad a "computer" and one that stares me in the face when I see programs like this and iWork- is there anyway to print from the iPad? What about just e-mail files created as an attachment? How are files saved and accessed without any sort of file directory or "Finder" system?
Not sure how reliable this rumour is but:
"Sources who talked to Apple’s business unit also say the company is working on some additional features that haven’t been publicly announced yet. These include support for direct network printing from iPad apps, as well as support for accessing shared files from a local file server."
