Microsoft’s new tablet, the Surface, is supposed to make the iPad and MacBook Air irrelevant. It’s supposed to be the best of both worlds by being a tablet/laptop hybrid. Reviews of the Surface have been mixed, and initial sales reports are indicating that Surface RT might be in trouble, because no one is buying it.

According to new research by the Boston-based brokerage firm Detwiler Fenton, Microsoft is likely to sell fewer than 1 million Surface RT units in the December quarter. To put that number in perspective, Apple sold 300,000 original iPad units on its first day of availability.

Despite countless rumors suggesting it was on its way, when Microsoft unveiled its new Surface tablet late last week, a lot of people were surprised. It was a strange move by the Redmond-based company, who has traditionally focused solely on software and allowed other companies to worry about the hardware.

So why did Microsoft build its own tablet?

According to one of the company’s former employees, it took hardware matters into its own hands when it realized it couldn’t rely on PC makers to make the same bets Apple was making. You see, Apple has taken some incredible steps to make its iPad the behemoth it is today. And rival companies just weren’t willing to gamble.
