Microsoft charges OEM's a significant amount of money to use Windows on their hardware, Google gives Android away for free.
So, the Surface is able to undercut the OEM's on price significantly.

I'm sure it's not $85 per device for the license but the point still remains.
Google, like Amazon is able to sell their tablet at that price at a small loss or no profit because of owning Google Play and selling content through it and the 30% cut of app revenue(Google does no curating of their apps so their costs are less than Apple's).
Not to mention early access to the OS, while all other tablets in the market are using the older version ICS.
How can HTC match that? They couldn't. So they stopped making Android tablets, same with LG.
