Yeah, I've seen that before. I'm not talking about just that. What I'm talking about is having the full screen mode Apple is developing will have support for turning the app into an iPad version with little effort. Basically, by following their API and implementing official full screen support, when the time comes to implement Mac to iPad support like I'm describing, instead of seeing the Mac's desktop, your seeing the application on your iPad in an "iPadified" version of the app.
