Not to mention that if you warm up the engine quickly, you'll be getting cabin heat for free.
One of the several reasons that I don't really like the Prius design is the fact that it has a pure EV mode at all. As others have said, it's not really efficient to drive in EV mode, then recharge the battery from the motor. With the Insight + MIMA, virtually all my battery charging comes from braking or going down hills, so it's "free" energy that'd otherwise be wasted as braking heat.
