The latest upgrade to the iPhone software is growing on me. I downloaded it on Friday when it was release and was able to put the enhanced Maps feature (with Google street view) to good use in Manhattan on Saturday. I really like the public transportation routing information--a practical alternative to the driving directions. And downloading podcasts without having to sync with the Mac is a great addition, too.
And since I'm on the subject of technological progress, the Google Mobile iPhone app with voice recognition is just awesome!
