Earlier today, Asus posted an official page for the 3G version of the Transformer tablet, which is identical in almost every way. It has the same 10.1" screen, Tegra 2 processor and optional keyboard dock. The only difference is a slight difference in battery life with the keyboard dock, which has been lowered from 16 hours of the WiFi-only version to 14.5 hours for the 3G version.
The 3G Transformer will be labeled with the TF101G model number and is due out in Europe near the end of August and should be coming to North America soon after that. In Europe, it'll cost 499 euros for the 16 GB version and 599 euros for the 32 GB version. In America, pricing will shake out to $499 and $599 for the 16 and 32 GB versions respectively.
