I'll talk about the Mac app store in a boo very soon actually. Suffice it to say I agree with you and have a few more thoughts to share.
Regarding the touchscreen interface for computer monitors, it would seem Steve Jobs agrees with you. He specifically said at the Macbook Air launch that touch screens want to be horizontal and that holding your arms up too long makes them hurt.
I agree with all of that but I think you're missing the point here. The point is that computers are changing into something else. At the moment that something else is a mobile phone but perhaps it'll become something more like a phone/iPad. These new style computers will suit the majority of people but probably not us dinosaurs so much. We'll still want our "truck" computers while normal people prefer their "sports cars". And the sports cars will be what our children grow up using. Touch will be the norm to them. More normal than a physical keyboard and mouse. And they'll get scarily good at using them to achieve what they want to do.
I'm not a fan of the idea of interfacing with my computer via touchscreen. At least, not exclusively. It's one thing to hold a device in my hands and interact it with it on a touchscreen. It's another thing to do have to do that with a monitor that's on a desk, facing me in the traditional way a computer monitor does. It just doesn't seem very ergonomic/practical.
As far as Apple bringing the App Store to the Mac OS, that makes sense from their standpoint. They can practically maintain complete control over the software delivery system. Why wouldn't they try it?
