First any discussion at this point to what the licensing deal is in regards to is speculation.

There is nothing wrong with licensing MS Tech and layering it on to Android or any other product if it makes it better for the consumers. What in the end is more important is how it is used and if HTC can create a new patent about how it leverages the MS tech in coordination with its own tech cheers for them. That is innovation. Sometimes it makes sense to buy over building from scratch especially when considering how important time to market is in this space.
