Microsoft is finally launching its Surface 2 tablet with LTE support. Priced at $679, a 64GB LTE-ready version of the Surface 2 will be available from Microsoft Stores and Best Buy tomorrow. Microsoft previously promised support for ATT LTE and Vodafone internationally, but only the ATT model will launch tomorrow in the US. Despite this, the Surface 2 with LTE will ship unlocked with support for LTE bands 4, 7, and 17.
