Regarding the 4th point, what I love from text fields (including text areas) in Mac OS X is that I can use Emacs-like key bindings so, to go to the end of the line, you can press Ctrl-E and to go to the beginning of the line you can use Ctrl-A. You can even use Ctrl-K to “kill the line” (something I use a lot) so you can make a Ctrl-A Ctrl-K to erase the URL in Safari.

But since I love Emacs key bindings (I used Emacs a lot), maybe it fit’s my needs and not those of every Mac user. This is the technical document where Apple explains the way Cocoa applications use the default key bindings and how to customize them!

Point 2 is a celebrated feature of Mac since the earliest Finder days. Having a dedicated toolbar anchored to the top of screen works for Fitt’s Law, in that the screen edges are “infinte” therefore you can fling your mouse against the top of the screen and hit the menu easily. Windows menubars-on-apps requires a more finegrained target for the mouse to hit.

Point 3 – this is just your habit speaking, they are simply different keys. I appreciate the fact that I can task-swtich both forwards and backwards on Mac (command-tab is forward, command-tilde is back… H or Q on a highlighted app Hides or Quits… very fast)

Point 4- interesting observation, I am always bugged by the fact that Home and End seem to do nothing at all when browsing the web, or often only one works.
