Why Tablets Will Fail: They're too big to fit in your pocket. They're awkward to use in most normal situations (ie, sitting at a desk) They will require a case for screen protection. Perhaps a case that folds open -- kinda like a laptop. Current software is designed primarily for keyboard/mouse input. Using a software keyboard and a stylus offers very little to most users who type faster than they can write. (that's one of the reasons type writers were invented in the first place, who wants to regress at this point?)
