Toshiba shows off 5.1-inch tablet prototype with 21:9 aspect ratio
Toshiba hasn't been a pioneer of smaller tablets. In fact, only recently did the company get into sub-10-inch ones when it released its 7-inch Thrive. But I truly think they could be pioneering something quite special, and it might start with the prototype you see above.
It's a 5.1-inch tablet, but unlike other tablets with 16:10, 16:9, or 4:3 ratios, this tablet has a ratio of 21:9. Obviously, it makes this device stand out, but what you may or may not know is that 21:9 is a filmmaker's preferred aspect ratio. It's what the final film is sent out in, and that's why you see the black bars on the bottom of your HDTVs.
This is why I think Toshiba is thriving to produce a new breed of tablets. In keeping with a very wide aspect ratio, Toshiba is allowing the full movie to be played on the screen; that is, no bars, no cut-offs. Anything that would distract from a movie simply vanishes.
The finalized device will be released at some point this year. In the meantime, I think we should all speculate what will be inside this rather odd device. I'm placing my bet on a very powerful GPU to be able to play high definition video clips.
