General Dynamics has been offering the Itronix line of rugged and ultra-mobile notebooks for a long time. In fact, the latest version called the GD2000 looks almost just like the MR-1 from back in 2008. The hardware under the hood is different though. The new GD2000 makes use of an Intel Celeron M ULV722 processor running at 1.2GHz and sporting an 800MHz FSB. The machine has 2GB of DDR3 RAM plugged into a MicroDIMM slot. The video card can use up to 256MB of that RAM.
