What's the difference between Surface and a touchscreen ultrabook? Not much really. In many ways a windows tablet is an extension of the laptop market. All the people I know with windows tablets essentially use them as laptops. So when you look at windows tablets this way it makes sense that windows should do well with tablets.
With phones it's differen. Phone is not an extension of a market that MS already dominates. Hence outside of supplying business, which doesn't care so much about apps, windows phone will struggle.
