While we typically stick to iOS (iPhone, iPad, and iPod touch) products, today's announcement of iLife 11 from Apple can't be ignored. The full screen interface for apps like iPhoto 11 look remarkably like a tab view app, with assorted buttons on a black gradient bar at the bottom of the screen. Now that iOS devices are outselling Macs, and the halo effect (iOS customers becoming Mac customers) is in effect, the tail is wagging the dog and we can expect the Mac to adopt iOS features. I'm guessing a touch screen interface can't be far away!

No touchscreen coming...
If you listened to the whole event you'd would have heard Steve make a point that touchscreens on laptops/desktops don't work. That's why the trackpad supports gestures.
Touchscreen
Apps on my mac
Todd,
I was delighted to see that apps are on their way to my desktop. BTW I have seen on the web, designs for an imac, similar to the old lampshade imac, that allows for the screen to be lowered into the horizontal position that Steve indicated was the ideal touch surface. So I am hopeful that a desktop touchscreen hybrid is in our future. It would just be great to be able to surf the web and read e-mail in the horizontal position, then flip the screen up to write longer posts or word process. I have a dream.
