If you are in the market for a rugged laptop, check out the GD2000 fully-rugged PC from General Dynamics Itronix. It features a 1.2GHz Intel Ultra Low Voltage Core Solo processor, a highly sensitive GPS and a 5.6-inch daylight-viewable DynaVue (1024 x 600) touchscreen display.
There’s also a hot swappable Lithium-ion battery pack, so you can replace the battery without system interruption. That’s pretty handy all by itself. A MicroDIMM memory expansion slot gives you increased memory space and it has an ergonomically designed keyboard.
