"There were also a couple of mild unfortunate surprises. First, Microsoft has removed the "squirting" feature, which let you send songs directly from one Zune to another. This feature was supposed to be a big selling point of the first Zune but was crippled by unreasonable rights restrictions that let you play songs only three times or within three days (whichever came first)."
This isn't something I noticed missing when I was doing my videos on the Zune HD, but it's definitely not there. Even if someone decided it was no longer a feature they wanted to offer for sharing music due to pressure from the music studios, why remove it for sharing pictures and podcasts? The wireless sharing feature wasn't something I used daily, but at least a dozen times a friend of mine has brought his Zune over when we've been hanging out together and we've shared music back and forth. It's a feature that the iPod doesn't have, and if the Zune HD becomes a success, it's a feature that would have become more useful as the market grew. So why did they take it out?
