Google Voice: One number for life

If you think Google is everywhere in your collection of computers and devices, you're right. The omnipresent online behemoth is at it again with Google Voice, which is coming to a cell phone near you.

Through the app, users can search the Web, send e-mails, create documents, modify spreadsheets and update to-do lists by using Google (GOOG). Google Voice makes it possible to choose a single phone number, through which one can take calls on any -- or all -- of one's phones.

To encourage use of Google Voice, Google has already created applications for Blackberry and Android phones, but it has yet to produce something for the Apple iPhone. However, as Google Voice co-founder Craig Walker told TechCrunch's Michael Arrington, a Google Voice iPhone app is already in the works.
