Modularity is a good thing if we can each select our favorite keyboard and then keep using it with many different phones. Not so much if it's just a device that splits in two.

As interesting as it sounds, I don't see users constantly attaching and detaching something like that. They'll use it either always or never. First case, it's thicker than it could be. Second case, it's an unnecessary cost.

Can't wait until we get integrated projectors, though.
