Lenovo's K-series smart TV range has officially launched in China. We got details last month of the 6,499 yuan ($1,030) 42-inch K71's release, but the range goes all the way up to the 55-inch K91 which retails for 14,999 yuan ($2,378). We were pretty impressed by the K91 when we checked it out at CES earlier this year — the combination of Snapdragon S4 processor and Android 4.0 gives the interface and games speedy performance, and features like face and voice recognition worked well enough. There's no word on an international release for these TVs, but Lenovo said it wanted to launch in China first to secure content deals.
