Tablets, tablets, everywhere!  At the Unpacked event of the Mobile World Congress, taking place in Barcelona, Samsung introduced to visitors its Galaxy Tab 10.1, running on Android 3.0. The second-gen device is larger in size than its previous counterpart, envisaging a 10.1-inch display, lighter in weight and more ergonomically created (we love ergonomics).  The Galaxy Tab 10.1 features an Nvidia Tegra 2 dual-core processor, an 8-megapixel back-facing camera and a front-facing 2-megapixel camera for video calls.

Long time competitor Samsung, on the other hand, debuted the LG Optimus Pad, also running on Android Honeycomb OS, with a smaller display (8.9-inch) than its predecessor, a 3D recording feature and 1080p Full HD decoding so you can transfer high-quality video from your Pad to your TV without any picture quality loss.

The Android OS is becoming more and more popular, as it is now considered to be the second most popular OS on the US market.  In a week’s time, the US market will make room for the much-awaited Motorola Xoom that will come at the price of $799, running on the now famous Android 3.0 OS.

Android Honeycomb has been long awaited for as some might argue that the current Android 2.2 version of the OS is responsible for the bigger number of Galaxy tabs being returned (13% return rate in December 2010) in comparison with iPads (2% return rate).

All this hassle in the OS market is forcing competitors to put their best foot forward in order to stay competitive.  We recently covered Dell’s latest preparation for its new 10-inch tablet running on Windows 7 OS aimed at business markets and HP’s Touchsmart PC running on webOS.
