I am aware of vim, but don't find its working style comfortable. It's true that vim can work well on a plain keyboard without needing arrow keys, Ctrl key, home/end/pgup/pgdn, shift-selecting, mouse, etc.

I like being able to type and select at any time, without having to remember which mode is active. Also, using Dvorak destroys the intuitive hjkl keys for positioning.

MacBook Wheel was great satire from The Onion ;-D. It vaguely reminds me of how annoying it was to type passwords and search terms on the Apple TV remote's D pad. For home theatre PC use, it seems most my friends choose a Logitech Wireless Touch Keyboard K400.
