Hi, I want to buy a tablet to use on my motorbike. Here are my needs: 1) Has to Charge FROM USB (off a 12 Volt Battery - cigarette charger). 2) Capable of Gaming (I spend long periods of time waiting at terminals etc....). 3) USB, HDMI, HD Video Playback. 4) GPS (Can I get this through a dongle?) If not I will need this, I ride in very remote areas. 5) 3G (I think a dongle will sort this out!!!) 6) Large Screen c.10 inch. Budget = c.100-200 USD I've done some research and I think the Zenithink zt280 may be for me (if a USB GPS dongle will work), What do you think?
