Last week was a huge week for news surrounding smartphones and iPad-like tablets. I mentioned a few weeks ago how the market was moving to vertical integration, which was placing platforms like Android at risk, but I didn’t expect HP to move this quickly by buying Palm and getting its own OS. In addition, the lawsuit from Apple targeting HTC’s Android phones, coupled with HTC having to license even more code from Microsoft to cover the same phones, has likely turned Android into the most expensive OS in its space.
