The Surface with Windows RT has been on the market for a few months now and many are starting to wonder how many units Microsoft has sold; UBS is placing that number at 1 million units sold to date. From Neowin:

Microsoft has been aggressively marketing the Surface with Windows RT and we will be curious to see how they advertise the Surface Pro without creating consumer confusion.

Microsoft’s next iteration of the Surface will launch later this month and will feature Windows 8 and an Intel processor. This version of the Surface will be more powerful (and more expensive) than the Surface with Windows RT but many expect it to sell better as its target market is much wider than the Surface RT.

While we are optimistic that Microsoft will release Surface sales figures they may remain quiet on the numbers much like they have done with sales of Windows Phone 7 and 8.
