I love my TN7. I dumped an HP Slate 7 Extreme after trying it out for several weeks and haven't looked back since (I pity the fools still stuck on 4.2). One of my major concerns with both is the usb port. Many have reported failures. I think it is more of an issue with the usb cable that came with the tablet. It is extremely inflexible and too short placing a lot of strain on the plug. A much smarter idea is use a phone charger 99% of the time. The cord on a phone charger is so much more flexible making it very unlikely of damaging the port.
