If you've been thinking about taking a plunge into the Windows RT world but wanted a tablet cheaper than Microsoft's Surface with Windows RT, you're in luck - you can currently get the ASUS VivoTAB for $399.

The ASUS VivoTab is a nice alternative to the Surface with Windows RT. It offers a 10.1-inch Super IPS+ panel with 1366 x 768 pixels resolution, Nvidia Tegra 3 quad-core processor, WiFi 802.11 b/g/n, 32 GB internal memory, microSD slot, 2-megapixel front-facing camera, 8-megapixel rear-facing camera, and all of these running on Microsoft's new version of Windows for tablets with ARM procressors.

The tablet comes pre-loaded with Microsoft Office RT (Outlook not included) and looks to be a healthy alternative to Microsoft's more expensive Surface with Windows RT tablet. It's all wrapped up in an ultra slim design with metallic finish and priced at $399.

The VivoTab has a very thin design and is one of the lightest Windows RT tablets available. ASUS also offers a very cool accessory called the ASUS Transformer Keyboard Dock, which turns the tablet into a laptop alternative by adding a keyboard, USB , audio ports, and extending the battery life to up to 15 hours of continuous use. It's nice having the option of using it in tablet mode and netbook mode through a clever accessory.

Windows RT has had a slow start since it's more of a stripped down version of Windows 8 but at $399, it is worth taking ASUS VivoTAB for a run.
