I can't believe...I take that back. I CAN believe some of the responses from the typical fanatics on here. But regardless, Apple should simply license iTunes sync support to companies like Palm. Now that DRM is no longer an issue for music, any excuses Apple makes for not supporting more hardware even if the companies are willing to pay for that support just doesn't hold water. Not wanting to compete with other companies goes down that same road of conflicting interests of running both hardware and software businesses by the same company. A software only company would support as much as possible. A hardware company would pay to get support and one that does both tries to use one business market (software) to prevent all competition for their other market (hardware).
In these cases, supporting more hardware means more software sales (i.e. songs, etc. from the iTunes Store). Now why in the world would a company NOT want more sales from their store? Well, only when there's a conflict of interest that generates more money. In other words, Apple makes larger profits from iPod sales than selling the music in their store so it's in their interest to not allow anyone else to use iTunes. And basically, I read between the lines this warning basically means they will actively try to thwart all such functionality in the future. That probably IS illegal since it's active anti-competition (similar to Microsoft trying to prevent others from using hooks in their operating system to achieve similar functionality to what Microsoft themselves have access to), but they'll claim it's just "coincidence" that it no longer works in the future. But doing things like encrypting certain key files in iTunes so that 3rd party programs in the Linux world can no longer function with iTunes databases, etc. have already been done by Apple. They always claimed it had to do with their DRM encryption, but now that it's gone, it'll be all too obvious that they simply want to prevent as much competition as possible.
I wonder what will be next. Maybe if you want to release software for Snow Leopard, you HAVE to distribute it via the Apple Store online and iTunes like with the iPhone and give Apple 30% of your profits??? Crazy? I don't think so. Apple has already done it with the iPhone and iPod Touch and they seem to believe because they're a smaller player than Microsoft that no rules apply to them and they're free to do any dirty underhanded tricks they feel like doing when it comes to the Mac market place. The fanatics wouldn't mind. They'd just remind us that it's Apple's operating system and they're allowed to do anything they want with it including telling you that you must give them your first child if you want to use OS X. After all, you can always go to Windows if you don't like it. You have no rights as a consumer as far as they're concerned.
