Apple's iPhone IP, to me, was what excited me most about all this iPhone/iPod touch business. Not the fact there was a touch screen.
I viewed all of this patented iPhone technology as an assurance that it would be a while before the competition could compete with anything iPhone OS related. This was Apple's BIG advantage.
What I find interesting is that "touch" has become such the buzz word. Reminds me of the effect the iMac had on all things consumer. After those colored iMacs hit the scene, goofy colored plastic crap was the way to go for the next decade. Today, every handset manufacturer, every digital camera, remote, monitor, etc. is touting touch this & touch that. And the funny thing is, touch is only part (and I could argue a lesser part) of what makes the iPhone OS so remarkable & powerful. No, what makes the iPhone so dominant is the integration with all things digital.
Sure, any handset manufacture can make their device require touch input. So what. But does their Mail, Calendar, photos, bookmarks, music player, maps all play nice with their computer back at home?
This is where Apple has a clear advantage over everyone else.
And I think they should defend their patents just as Tim is suggesting. No less.
