Not sure if I've spouted crap, but that's what I seem to have to keep usage down and battery life up :P
Definitely worth getting a silicon skin or another type of case. It's hard to say if it will break easy or not, it really depends where you drop it from and how it lands, but mostly you'll get a few scratches on the corner (judging by my friend's Nexus One hitting the floor) :P
