Lenovo announced the IdeaPhone K900, a monster of a device not so long ago, but the unique thing here is not the format, but rather the CPU inside. This device packs a dual core Intel CPU with a 2 GHz frequency.
The K900 was demoed to us at MWC 2013 and it seemed like a pretty appealing piece of gear. It adopts a Clover Trail+ CPU and its display is a 5.5 inch Full HD one, with a pixel density of over 400 ppi. The phone is only 6.9 mm thin, with Lenovo claiming that the device is the thinnest phablet ever and I tend to agree.
The materials used here are polycarbonate and stainless steel, making the device feel and look premium. This is also a handset with sharp corners and a rectangular shape, while its competitors are more rounded. The device also uses a 13 megapixel camera with a Sony Exmor backside illuminated sensor and a bright F/1.8 lens. The device runs Android 4.1 and supports back customization with 4 metallic backs.
