i don't know what you specifically need, but if you want light, fast, and tough under travel then you need a Toughbook CF-18. Got mine for $250 on ebay. 1.1ghz, 1gb of ram, 120gb hdd, wifi, etc etc. Also has tablet mode, which comes in handy. Thing took a drop from two floors up onto pavement and walked away lightly scratched. Last night i forgot it in the driveway and it was frozen in the snow. Let it thaw out in the sink, wiped the wetness off and works perfect.
