Intel's 2012 Developer Forum took place last week in Beijing, and reports of innovations are starting to make the rounds, including this hybrid tablet / ultrabook prototype that Intel has dubbed the Letexo. We actually saw this prototype back at CES, but unfortunately Intel hasn't released any more information on what's running under the hood — it's running on Ivy Bridge, and has the same rather unique form factor. It can be used in a standard tablet configuration, but users can also push the screen up and prop it against a built-in stand to reveal a keyboard, letting it be used in a more traditional laptop-style format. Also of note is the fact that this prototype was running Windows 8, though that's not too surprising, given Intel's interest in Microsoft's next OS. It sounds like this device has a similar form factor to Toshiba's Portege M930 that was saw back at CES, as well as the Asus Eee Pad Slider — though it does look significantly slimmer than the Toshiba. If you're curious, Intel has posted a video with some highlights from IDF 2012, which includes a quick look at the Letexo.
