IMHO: What each and every gadget should have is a mapplet link/tab with rich purchasing capabilities associated with it - i.e. financial features & location based geo...all mashed up ;) Hey, if you've got me interested in your movie at least show me where there are cinemas playing it nearby my present location...and let me buy tickets for two seats in row H...within the gadget!
