I'm on my second Panasonic Toughbook. It's got a VERY long battery life (advertised as 7 hours, but depends on what you use it for obviously), it has an integrated DVD drive (not peripheral), and it weighs only 3 lbs. I take it everywhere. It's called a Toughbook because if you drop it, it still works. (So far I've tested that up to 30 inches.)
