Today sees the launch of a new tablet PC from Motion Computing, who are updating their M1400 line in the new LE1600. They're really billing the battery life on this thing, which looks like the first slate tablet using the Intel Centrino processor — the standard battery only gives 3+ hours of life, but when combined with an optional hot-swappable extended battery, you're supposed to be able to get a whole day's worth of work on the go. It's loaded with a bunch of other nice features, as well: 12.1-inch XGA screen, DVI-D out, WiFi, Bluetooth, IrDA, gigabit ethernet, and an attachable all-in-one mobile keyboard and mini docking station. It's a bit lighter than the M1400 at 3.1 pounds, and thinner by a quarter-inch. You'll be able to get a few different configurations, but the basics will include a 1.5GHz processor, 512MB DDR 400MHz RAM, and 30 or 60GB hard drive. It's available now from resellers starting at $2,199, and there's also a Celeron-based version (the LE1600c) that'll go for $1,899.
