It's good to know that not only the low and middle-tier Itune users are feeling some frustration with their latest "updates." The high end is also feeling the same pain. Here's an update from Roku, a high-cost network music player company,
"With the release of iTunes 7.0 today, Apple has changed some of the underlying technology that allows the SoundBridge to communicate directly with iTunes. We hope to have an iTunes 7.0- compatible release of the SoundBridge software soon; however, at this time all SoundBridges are incompatible with the music sharing feature of iTunes 7.0. We recommend that SoundBridge owners wait for a SoundBridge update before upgrade to iTunes 7.0. Users wishing to upgrade to iTunes 7.0 (or who have already upgraded) can install the free Firefly media server to share their libraries with the SoundBridge. Firefly is available at http://www.rokulabs.com/firefly."
At least Apple doesn't discriminate as they tighten the noose.
