Breakfast briefing: The guns come out at Mobile World Congress

• The big news this week is likely to come out of Mobile World Congress , the phone industry's annual shindig in Barcelona . Our own Richard Wray is there, reporting on plans for a number of companies to link up to offer a rival to Apple's app store . • Another competitor looking for more success in the mobile world is Adobe , which says that it's planning to offer Flash and AIR for Android . There's no Flash on the iPhone, as we've discussed previously , but it looks like Adobe wants to try and get Apple's competitors to support its runtimes. • A couple more things to ponder coming out of the weekend: BoingBoing points out that the state of Washington - which is facing a budget deficit of almost $3bn - could give Microsoft a $100m tax break and an amnesty on $1bn in unpaid taxes ; and Robert Scoble manages to argue pretty successfully why those who whine about the TED conference being too exclusive should stop moaning .
