The US might not see it immediately, but the world will soon get its first Firefox OS tablet. Mozilla has begun testing its browser-based operating system on tablets and has developed its own tablet prototype. Currently Firefox OS runs on smartphones and may eventually power smart television screens, but this is the first showing of it on a big-screen device. The Foxconn-built prototype isnt the highest-end tablet by any means, but its not the worst, either: specs just released say it will have a 10-inch, 1280 x 800 display, 2GB of RAM, and 16GB of internal storage paired to a 1GHz quad-core processor.
