Apple has posted its tech specs for the third-generation iPad, revealing a number of unspoken features and limitations. The page reveals that the new iPad boasts Bluetooth 4.0 support, as well as a considerably larger 42.5-watt-hour battery. The previous limitation of 720p AirPlay Mirroring remains—even when using the new device with the upgraded third-generation Apple TV announced today—but the new iPad is capable of streaming AirPlay video at full 1080p resolution. As in the past, the Wi-Fi version of the iPad lacks GPS hardware, while the newly-named Wi-Fi + 4G does not. Finally, the new model is slightly heavier than the iPad 2, with Wi-Fi models weighing in at 1.44 lbs. and 4G units weighing 1.46 lbs., compared to 1.33 to 1.35 lbs., respectively, for the iPad 2.
