There's a reason the iPad is such a successful product. It's not merely because it's so thin, so light, and looks so good you'd lick sugar off of its glass display. It's a hit because "When technology gets out of the way, everything becomes more delightful, even magical." Or at least that's what the iPad TV commercials have us believe.
Project Rimino is an exercise in how people can influence the ways technology works for them, instead of conforming to what technology already provides. Rimino is about cutting away all the technical intricacies of a powerful mobile device and simplifying the device and the UI to its most basic structures, so that we can use technology when we need it, but not be consumed by its entirety.
