> My MBP's touchpad is not so bad until I need to drag something, I've noticed I avoid interactions such as resizing that I do all the time with a mouse or a touchpad that has dedicated buttons.

Did you know that you could use a macbook touchpad like it has buttons? I've noticed it with my mother and my girlfriend (separate entities for the record) when I got them a macbook when their windows-based laptops almost died: they couldn't get used to clicking and pointing with the same finger, and fell back to their old habits of having a finger on the bottom left of the pad, and clicking that finger if they wanted to click/drag something.

So it kind-of knows what to ignore and what not to ignore / recognise intent of the user trying to do this.

When you combine this with "bottom right click = right mouse button" you basically have what you want!
