The new Hotmail — good for Microsoft services, not for mobile browsers

We’ve already discussed the new version of Hotmail that Microsoft demonstrated yesterday, with a focus on how it stacks up against Gmail. But one of the strongest impressions I took away from the presentation wasn’t just the ground that Hotmail might regain from Google and other competitors. If the new application, scheduled to launch this summer, does everything Microsoft hopes, it could also provide a real boost to the software giant’s other services and technologies.
