This will be a special, full-hour Yi-Tan call. Those of you who are snow- or cyclone-bound may appreciate the extra time around the communal fire.

Over the past five years, Google and Apple have transformed the technology platforms that dominate the software, Internet and entertainment businesses. Now app stores and tablets are popping up like paperwhites in spring, video over the Net is looking pretty viable and magazines may -- repeat, may -- have found a path to the future.

Developers and investors have to place bets on which platform will be the better opportunity. Android or iOS? Native apps or web apps? 

With Al Chang, Carl Johnson, Nathan Brookwood and Dave Bujnowski, let's discuss:

• One phone to rule them all, or 4,231 phones? What do developers say?
• Will tablets cannibalize laptops, or are these two distinct markets?
• What happens at Apple if Jobs isn't around? How long will current momentum last?
