Based on my experience the last time I upgraded my iPod Touch, I was a bit hesitant when it came to this release.  I was pleasantly surprised to see that none of the 3rd party apps were broken after the upgrade this time around.  So far the iPod Touch has been rock solid on this release.  The 2.0 release was pretty solid too, so it’s nice to get some stability back. (one thing that was certainly missing in the previous release)  The most noticeable new feature mirrors the Genius feature of the new iTunes 8.  I’m interested to see how well it works.  The Genius feature is supposed to suggest music you’d like based on other things you have.  It can also create playlists that go together based on the same technology.  I’ll have to give it a whirl the next time I’m on the bus…
