LG just officially announced a convertible tablet dubbed the Tab Book 11 that runs on Android but with PC-level specifications.
The tablet is powered by a dual core Intel Haswell i5 4200U ultra low power CPU. Although it is still to be determined if Android is properly optimized for the i5, the processor is ridiculously overpowered for a light operating system such as Android. LG could have opted for the Android 4.4 Kitkat instead of the Android 4.2.2 jelly bean included. Furthermore the device comes with a 11.6 inch display with FullHD resolution, a massive 4GB of RAM, USB 3.0, a fast 128GB solid state drive and a microSD card reader.
Additionally the tablet comes with a sliding keyboard with a dedicated Android home button and weighs in at a little less than a kilogram. Although these specs are meant for a 64 bit operating environment, the recent reveal of the 64-bit Android L could bring hope in the near future for devices that want to take advantage of more powerful processors. Apparently, a LG representative informed Android Police that the Tab Book 11 can be purchased with both Windows and Android in a dual boot configuration, although no dates or pricing have been announced for now.
