I've personally pondered using mifi vs using a usb wireless card. The drawback to the mifi would be having to carry around a larger device in addition to the tablet. The drawback to the usb card could be driver issues...Still, I bet you could do something like what they did with the N810 here to house a USB wireless card internally: http://talk.maemo.org/showthread.php...ight=N810+card
