This same old, tired and lame discussion comes up every single time there is an iPod software update.

It should be no surprise by now that only the current model iPods will ever see feature upgrades. It's been the same now for at least 2 years, it's nothing new and it does no good to complain about it.
Apple is in business to sell new units and make money. If they didn't add new exclusive features to the latest generation iPods, there wouldn't ever be any real incentive for anyone to upgrade. The same will happen when the 5G models come along too, it's not going to ever change. Apple isn't the only company that works that way either, they all do. A 2 year old DVD player for example isn't ever going to have all of the same features as the latest and greatest model. That's just reality. And as a few have so rightly pointed out, the 1G/2G/3G iPods haven't lost one single feature that they've always had from day one when they were purchased either, so nobody is being cheated out of anything.
