Google About to Buy A Ticket to the Mobile Web?

Saw a posting on Slashdot today reporting rumors circulated by other bloggers (presumably in the know...) that Google is poised to gobble up Opera Software. Given Opera's reach on mobile devices, if this rumor proves true it could provide Google a convenient vehicle for gaining a toe-hold on the mobile web. It could also give XHTML+Voice some interesting momentum, as speech-enabling mobile XHTML browsers makes a lot of sense, given the usability constraints. Particularly when trying to fill out a form via a phone keypad. Another interesting angle though is that most of the text entry you do for existing Google apps (think search, gmail, etc.) would typically require some sort of dictation engine, not grammar-based recognition.
