I have a Pre and appreciate Palm going out of their way to maintain iTunes operability...since I had iPods and iPhone 2g AND 3G prior to this I'm used to managing my media in iTunes for years now. Being able to plug in the Pre and continue to use iTunes is a huge plus.
My guess is Palm is trying to bait Apple into this debate/battle since it can easily lead into anti-trust/monopoly law suits against Apple for not allowing 3rd party devices to sync with iTunes and the content that YOU OWN as a user.
It's no different than if Apple would only allow Apple branded USB Hard drives to work with Mac and you couldn't use Seagate or Western Digital, etc. Then people would be bitching, I don't see this being any different.
Watch out Apple...it's a slippery slope.
