Unless MS release some actual sales figures, there is no way to know if 'sold-out' equates to hit or lack of stock.
Will need Surface Pro to sell like a hot cake for few more months to put these anti people into submission.
I think that the last paragraph of the article, sums up the situation quite reasonably.
This machine is not what the Surface Pro could be, but it's a pointer to what it should be. The problem for MS is that they have a long history of snatching defeat from the jaws of victory, and if they allow this opportunity to get away, you can bet others will quickly capitalize.
