Word on the street is that Microsoft and Nokia are having a teleconference to announce an "alliance" between them. Could this be a collaboration with Nokia's Symbian Mobile OS and Windows Mobile? Its hard to think what they will actually be collaborating in since, they've got their own platforms already. Certainly, not a phone. 

Or we could be wrong. Our guess is some kind of tablet or netbook powered by both their technologies in an effort to steal the thunder from Apple's rumored tablet coming out in September or October. We're still guessing, so check back tomorrow for updates.
