T-Mobile’s G-Slate, the first tablet to pack a 4G radio out-of-the-box, is now available from T-Mobile. The G-Slate has an 8.9-inch 3D display, runs Android 3.0 (Honeycomb), can record 3D video, and sports a NVIDIA Tegra 2 processor clocked at 1GHz. We found the Android user interface to be a bit sluggish during our review, but we hope that T-Mobile fixes that snafu with future software updates. Android enthusiasts should still find a lot to love in the G-Slate, which is available online and in T-Mobile stores for $529.99 with a new two-year contract.
