i got a tw700 tablet for this exact reason, i needed something to take with me thats not huge, i didnt want to spend much more than 30 bux, so i trolled ebay for a while and found a good deal

its a cool tablet but way under spec'd, cant really do much "computing" with it, but if your only using it for hotwire, other esc software, and maybe browsing, its pretty cool... full size usb port, and full version of windows 8, not mobile.... works fantastic with the hotwire, i think theres another version that has more ram, had mine for about 7 months.. so far so good
