Quanta, the company that produces plenty of the hardware you know, love and fantasize about today, is showing off a new tablet prototype at NVIDIA's booth. The reason for its location is the Tegra 2 chip inside (you can see it in the nude over here), which can comfortably drive 1080p out via a HDMI cable and into your nearest HD display, while offering brain-melting battery life. Listening to music with the screen turned off can be done for 140 hours straight, and HD video playback can go on for up to ten hours -- both figures that make current battery efficiency look kinda silly. With WiFi, 3G, and Android for an OS, this prototype could be quite a nice little device, but right now there are more things wrong than right about it. The display is shockingly unprotected from the back, and we saw ripples appearing on the screen from our fingers supporting the machine. Furthermore, the touchscreen missed plenty of our taps, leaving us with a sour taste from what looked like a tasty little morsel.
