According to AT&T's website, the 4G speeds are currently available in the Dallas-Fort Worth, San Antonio, Houston, Atlanta and Chicago areas, though more are expected to become available soon. AT&T plans on expanding its 4G LTE coverage to an additional 15 major metropolitan areas by the end of the year.
Based on early reports, the 4G speeds of the Acer Iconia A501 are much slower than other tablets currently on the market. One report saw only a 1.9 Mbps download and 1.2 Mbps upload speed. These numbers are very bad, especially considering the fact that the Samsung Galaxy Tab 10.1 4G LTE version saw 19 Mbps down and 5 Mbps up on Verizon's 4G network.
The tablet itself, however, runs Android Honeycomb version 3.0.1 an Nvidia Tegra 2 dual-core processor at 1GHz. In addition to that, it also comes with 16GB of internal memory. Pricing isn't too outrageous, especially considering some of the other prices you could be paying for a 4G tablet. If you opt for the Acer A501 on an AT&T data plan, you will have to fork out $330 on a new two-year agreement with a minimum $35 per month data plan. If you go without the commitment, you can expect to pay $480.
