I'm currently registered to attend AndDevCon III in San Francisco in a week (I've got my hotel, air and registration booked). But because a loved one is having health problems I may have to cancel-out (good thing I have trip-insurance!) Question: If I have to cancel, are there any other major Android Developers' Conferences in North America this year? I'm not counting Google I-O because that's about a lot more than Android. Thanks in advance!
