This attitude shows their company’s character. Microsoft is pure software maker as shown by its name. They don’t think making hardware makes large amount of money. Google is standing on Internet, so google make their OS as a entrance of Internet. They don’t care about its form. Internet is ruled by Google. We have to ask Google our destination before moving on Internet. On the other hand, Apple is still making their own operation system. I think it’s for pursuing better user experience. It means Apple is making user experience.
