Microsoft's Surface 2 sold well in the fourth-quarter last year, racking up $893 million in revenue, according to Microsoft. It may be a slow start to thing, but it looks like they're finally making some progress.

The sales were reported in Microsoft's fiscal second quarter, and compare to revenues of $400 million in the previous quarter.

The company has since cut the price on the Surface RT, expanded distribution and introduced the Surface 2 and Surface Pro 2, which improved many of the initial tablet's falws. Still, the Surface accounted for just  2.3% of all tablet-based Internet traffic, according to Chitika. That compares to 76.1% for Apple's iPad.

The stats are pretty encouraging for Microsoft but they still have a long way more to go to catch up to the iPad.
