Microsoft Surfaces Tablet Gains - WSJ

Persistence pays, at least in terms of revenue (although, from later in the article, Surface is still less than 4% of Microsoft's total revenue for its latest fiscal year)

"Microsoft said sales of its Surface tablets totaled $888 million for the most recent quarter. That brings the company’s tablet line to about $3.6 billion in revenue for the fiscal year ended June 30.

That measures up with only about 15% of Apple’s iPad revenue for the same period, showing that Apple still dominates the tablet business. But there is another interesting point to note: Microsoft’s Surface revenue is up 64% for the fiscal year, while Apple’s iPad revenue fell 22% year over year for the comparable period."
