My 2 cents?
Apple cannot compete, how low cost can google produce these systems with everything already built out by google maps. If google starts producing low cost portables now as well, based on some pretty unix developed OS, a lot will change in the market.
Google doesn't want to change your life (or make it easy), it wants to BE your life, in every electronic way, on any platform, at a decent low cost. (and i'm not that happy with that, look at privacy on picasa. But a lot of people dont know, or dont care.)
What would Apple do if google would decide not to lend the app after a while? Go free? I don't think so. Apple is branding on price and status, and in times of economic crisis that is def not the largest part of the market.
