While the rumored Toshiba Excite is being flaunted off at the Internationale Funkausstellung (IFA 2011) in Berlin, its thicker predecessor–the Toshiba THRiVE–is on its way to the United Kingdom.

The Toshiba THRiVE will be called the Toshiba AT100 when it reaches the U.K.

The product page for the Toshiba AT100 is already up at the Toshiba Europe website and shows the 16-gigabyte model.  There is no confirmation yet whether 8-GB and 32-GB models will also be made available.  No pricing information has been revealed yet either.

The Toshiba AT100 runs Android 3.1 Honeycomb.  It has a 10.1-inch screen (1280×800 resolution) and a dual-core NVIDIA Tegra 2 processor.

One of the Toshiba tablet’s main attractions is its full-size ports for HDMI and USB.  It also has a MiniUSB port.  The removable battery is also an attraction, since other tablets feature fixed batteries.

The tablet’s removable battery provides about 120 hours of power on standby mode.  The larger-capacity battery pack accounts for most of its thickness and weight (0.6 inches, 1.6 lb).  The tablet is heavier than most other Honeycomb tablets.

The Toshiba THRiVE has removable, custom-color back plates.  It is likely that the Toshiba AT100 will also be provided with such back covers.

The Toshiba THRiVE is Toshiba’s first attempt to provide a Honeycomb tablet with laptop functionality and power and is expected to appeal to laptop users who may want to move on to something more portable.

Toshiba officials explained that the Toshiba THRiVE/AT100 leverages the company’s main strength–that of a laptop maker.  So, instead of making a tablet with extended smartphone functions, Toshiba makes the laptop more portable and lighter.
