Rugged PC builder General Dynamics Itronix on Monday became the latest company pushed into signing a patent deal with Microsoft simply by choosing to use Android. The firm will pay Microsoft an unspecified amount in royalties for every device it makes running the Google OS. Although GDI doesn't make any Android devices yet, the company's Strategic Computing Solutions lead Mark Johnston has used the deal to tout Android as a superior alternative for some parts of his company's currently Windows-only lineup.
