But I still prefer keyboard shortcuts, they juste feel more natural while the hands are already in "typing mode". I feel like there's a question of "waiting around". Even though I've always found the mac trackpad to be very precise, even for quick movements, you still have to aim for an icon, move the cursor to it, click, etc.

Now in the particular case of a macbook, where the windows will probably be maximized or not move around a lot, you may get some kind of muscle memory. But you still have to look around for the icon, etc. Whereas a shortcut is always the same, you press the keys and you're done, it doesn't matter where your cursor and / or window happen to be. I also prefer hidden icon toolbars, this allows me to gain some vertical space.

But, as another commenter said, some actions are easier with the mouse and wouldn't throw mine away. In my case, that's web browsing.
