I'm wondering what's missing from the iPad that stops it from being a viable "full computer" in its own right (no, this is not a thread to debate Flash, multi-tasking, or the lack of a camera, etc.). One main thing I think that's missing without requiring another computer involved is backups. How long before anyone expects Apple to release a Time Machine app for the iPad? And how would it work? Obviously it would work over WiFi, and would likely backup all Apps, emails, and the shared folder files, but how would the *interface* actually work? Apple are being very insistent that developers can't use a file system metaphor for accessing files on the iPad, but this makes me wonder how Apple could portray the Time Machine interface on an iPad without being able to show files and folders.
