If you want to experience the full web, you have no choice but to have Adobe Flash Player installed on your Android device. Today Adobe launched Flash Player 11 across all systems including Android. Hit up the Android Market to download Flash Player 11 now! The changelist is huge and mainly aimed at Flash developers, so let me paraphrase the whole thing for you to a familiar tune: It’s harder, better, faster, stronger.
Update: For those interested in Adobe Air, Air 3 has been released on the Android Market as well: download here.
