Android is certainly making its rounds these days, and T-Mobile is the second company to launch the OS on a tablet. LG’s G-Slate, offered through T-Mobile, hit the store shelves today and is the first tablet of its kind to offer 3D capabilities.

Any hopes of competing with Apple for the tablet PC market is kind of a no-go, what, with the heavy price tag which is $129 more than the iPad 2. While the official retail price of G-Slate is pegged at $529, users will also have to pay a mail-in rebate of $100 for a 2-year contract with T-Mobile.

The G-Slate is powered by a 1GHz NVIDIA Tegra 2 dual-core processor and features an 8.9-inch 3D display supporting up to 1280 x 768 resolution. A 5 megapixel 3D camera at the back supports 1080p video capture while a 2 megapixel camera in the front can be used for video calls. The rear camera also allows one to capture 3D images.

So far, the device has been received positively in the market and it has received slightly higher ranking than the Motorola Xoom in terms of performance.

 “[The G-Slate] is more comfortable to hold, the G-Slate’s build of Android seems more stable,” noted Michael Oryl of TechSpot.

The G-Slate will be able to render 3D display via the 8.9 inch screen though it requires the use of special 3D glassed to get the effect. The T-Mobile version of the G-Slate will come pre-loaded with a few goodies such as T-Mobile TV, Need for Speed Shift HD, as well as the Zinio e-reader. Also, T-Mobile had earlier announced they would also be making available a pair of 3D glasses completely free.

The G-Slate arrives just a day after the RIM PlayBook hit the market, however, the PlayBook’s arrival wasn’t met with much excitement.

According to a report from Reuters, in Toronto, only 5 people showed up for a 7am opening of Sears, while in Midtown, New York, only three PlayBooks were purchased off the shelf. The release date, originally slated for the first quarter of 2011, was reportedly pushed back due to a shortage of touch screen panels, which Apple had already allegedly obtained for the iPad 2.

RIM unveiled its BlackBerry PlayBook last fall, showcasing a 7-inch touch display and running BlackBerry Tablet OS, a new operating system developed by QNX Software, a company that RIM acquired last year.
