What will happen if Apple make a windows version of Macbook Pro and Macbook Air?

Recently I got two defective thinkpads and they were both returned, which broke lenovo's image in my heart.

I used to have an iPad and now an iPhone and they all gave me a great user experience hardware wise. Around me there's so many Macbooks, I came across that Macbook Pro is actually well designed, of more reasonable price/of better specs and of better quality and of better service compared to an average ultrabook, but a reason people don't buy them is because it's not native to windows, it's OS X.

I wonder how success it would be if Apple make a windows version(I don't mind if they put apple software on it) of their lines of Laptops. Any thoughts?
