The Nokia Lumia 2520 is only the second Windows RT tablet released in 2013 -- the Surface 2 is the other -- so if you're looking for a new Windows tablet with free Office, there aren't many to choose from.
The 2520 isn't the thinnest tablet on the block. In fact it's just as thick as the Surface 2. The Surface 2, however, can get away with its extra mass by including a built-in kickstand. No kickstand on the Lumia.
