Suggestion
I've been pondering how Apple could close the gap, and allow iPads to be better productivity devices... and I think an iPad/iOS App, that is effectively a virtual machine instance of one's main MacOS environment (perhaps synced with iCloud) would be a really neat solution... the device is then an iPad for consumption, and contains your full fat MacOS environment for when you have keyboard/mouse/trackpad pluged in, and need to do real productivity tasks, like moving files around / document management etc... it could perhaps be a slimmed down version of the MacOS environment (for example, if they want to protect their walled garden/App store, although I think that model is probably on borrowed time for anti-trust/competition law reasons)... anyway, that would allow me to go away for a couple of days and only take the iPad!
