I don't have to have it right near the edge. I can adjust that. Side scroll is along the bottom. It's just like scrolling on the right or bottom of windows. Pretty intuitive and works fine. The micro second it takes to move slightly over is not an issue.
And why would you want it to be anywhere else other than the edge? So that it's more likely to interfere with your normal cursor navigation?
And I'm not saying that you can't scroll on a non-Apple trackpad. I'm saying it's much better with one. And diagonally scrolling? Not going to constantly go back and forth between two different linear paths making micro adjustments.
I don't see why I would need to maximize a window. My windows are all set to the size that they need to be and there is no reason to change them. If I have a lot of applications open I can just hit Window Key + Tab and click on the application. Or I can hit Alt-Tab and click on it as well. Or just simply click on the program on the taskbar. Honestly I don't ever use the window key + tab, and the only time I Alt-Tab is when switching between two specific programs. Otherwise I just click on the program I want which is already on the screen in the taskbar. I don't see how it can be any easier than that.
My point was that I can use Exposé without having to use the keyboard, but, anyway, Windows Key + Tab is absolutely atrociousthe windows are in front of other, blocking content. And the taskbar is clunky when everything starts combining.
Notice that "Window Key + Tab and click on application" and "Alt + Tab + click on application" requires both hands to be attached to your laptop. I can accomplish the same thing lazily on a MacBook with just one on the trackpad.
To answer your question, I do always have both hands on the laptop when using it unless I'm just browsing the web. I can reach all the shortcuts that I need with my left hand.
And browsing the web makes up 80% of your time, no? If it doesn't, that doesn't mean it isn't for others.
