I've read quite a few complaints about the strength of the screen hinges on tablets, including that they allow the screen to flex too much for tablet use in the up position, a problem I've experienced myself with some demo models. So here's my two suggestions for what manufacturers should try: 1) Double hinging: hinge both the base and screen of the tablet to connector sections. With proper alignment, the double hinging would allow the used to flip the screen around to lie flat on the bottom of the notebook while still retaining the strength of a dual hinge setup like regular laptops have. It would require moving air vents most likely, but I don't think it would be insurmountable. 2) Screen locks: This one is so obvios I'm suprised nobody has tried it... simple take a regular tablet PC and mount the holes for extra hinges to the screen and mount retractable rods on the base... it would be locked in place like a regular laptop screen normally, but the rods could be retracted to allow it to fold into slate position. Hope I got the ideas across there. Of course, both would require a manufacturer to pick the ideas up.
