Microsoft Bob. Not because it was great, but because I think we need more exploration into alternate ways to interact with computing devices. I've seen plenty of people - even young people - doing things wrong because their mental model of how their devices are supposed to work is inadequate or incomplete. I've seen more than one person with hundreds and hundreds of browser tabs open on their iPads and smartphones, because they just don't seem to be able to incorporate the "tab" concept into their model of how their web browser works. And so they're constantly clicking and opening new ones without realizing they can switch back to ones that were previously open.
