The T-Mobile G-Slate has finally gotten some official pricing. For users looking to grab themselves one of these 8.9-inch Honeycomb tablets, the device will launch at $529.99 after a $100 mail-in rebate. If you missed the video of the device in action from CTIA2011, be sure to check that out to see just how smooth the device operates. While unfortunately there is still no official release date, T-Mobile has indicated that it would be later this spring, so it shouldn't be too far off. [T-Mobile]
