When a major player like Google comes up with a new mobile operating system that's better than the competition and is totally free, you would certainly expect handset manufacturers to be interested. But there's interested, and then there's interested. After lingering for nearly a year in the former category Motorola is now firmly moving to the latter, hiring and headhunting in an effort to build up a 350-person group entirely focused on development of Android phones. The company was one of the original members of the Open Handset Alliance, but seems to have waited for the release buzz from HTC's G1 before diving in head-first. There's talk that Nokia (and its "real phones") may be feeling the vibrations too, allegedly forming an internal team to do the same -- on the down low.
