So the "Back to the Mac" event ended up being a bit of a dud. The iLife update borders on laughable - iPhoto now comes with Full screen view! Really? I can't believe Apple has the gall to charge $49 for an upgrade. Pretty much the only memorable thing was the iMovie trailer templates, and even then that's pretty much a novelty feature.
Only a few choice details of Lion, the next OSX version, were revealed, but the direction was clearly spelled out: Apple intends to merge the iOS and OSX platforms. The inevitable conclusion of this would presumably be a multi-touch screen iMac, as previously discussed. If you accept that, then the choice to release the Mac App Store early is a little strange. By releasing early, the Mac App Store will initially be populated with Apps that would not be multi-touch capable. Most existing Mac software won't fit well into the new full-screen Launch Pad paradigm:i.e. this only makes sense for games and little else.
The idea that a multi-touch trackpad is like a multi-touch screen is absurd. The UI paradigms are completely different: A mouse cursor vs. direct manipulation. The focus on "multi-touch" vs. "direct-manipulation" is a clever smokescreen. The problem is that Apps that target one or the other must be constructed completely differently: For starters, UI element sizes and placements have to be different, but it extends even to the whole structure of an App.
My guess of what's really going on is that Lion will be multi-touch direct-manipulation capable, and the next iMacs will have capacitive multi-touch displays. Apple did not reveal this simply because they don't want to cannibalize existing Mac sales. The timing of Lion's release next Summer coincides with the next iMac hardware refresh cycle.
In many ways, doing multi-touch on the desktops (vs. laptops) first makes sense: Apple already has the tablet market cornered, and a multi-touch laptop will only serve to confuse. Multi-touch desktops, though, represent another brand new untapped market. If Apples does indeed go for that next year, they will catch all their competitors gunning for the tablet market by surprise, yet again.
