Adobe has just launched the new AIR 2 based [Tour de Flex version 2.0][1] which now contains almost 500 Flex examples! The new version has new AIR 2 examples (only available in the AIR version of Tour de Flex) including:

  * File Promises
  * Mass Storage Detection
  * Native Process
  * Open with default app
  * Socket Server

Also there are some great examples of the new Flash Player 10.1 and AIR 2 APIs including:

  * Gestures
  * Global Error Handler
  * Globalization / Internationalization
  * Microphone access

Those are some great examples but my favorite is still [Doug McCune's][2] [Physics Form][3] followed closely by the [real-time Tour de Flex Dashboard][4]. :)

If you already have Tour de Flex installed then it should auto update to the latest version when you launch it. Otherwise install it now using the badge installer below.
