Seriously though, where do you feel it's failing compared to other keyboards? As far as laptop keyboards go, it's one of the best I've used.
If you use Wordstar bindings, then control+q,control+s is start of line, control+q,control+d is end of line. Forward delete is control+g.
The Wordstar, Emacs and Vi keyboard bindings evolved in the days before dedicated keys for cursor movement functions, so they are useful as long as you have the requisite additional modifier keys. I.e., like when you are on a laptop with a limited number (or none) of dedicated cursor movement function keys (or with those same keys hidden behind odd Fn keystroke combos that differ between any two different laptops).
ctrl+a goes to the beginning of a line ctrl+e goes to the end ctrl+k deletes a line
A couple other recommendations, however:
BetterTouchTool: The MBP trackpad has a surprising amount of complexity in terms of recognizing gestures. BTT adds to that . http://www.boastr.net
Keyboard Maestro: Scripting and advanced keyboard shortcuts. Includes support for per-app shortcuts, which is pretty phenomenal. http://www.keyboardmaestro.com
TextExpander: Less practical when you're programming, but TE can be great for automating things you write often (email address, email responses, URLs, etc.) http://smilesoftware.com/TextExpander/
I had been using Windows for the previous 17 years or so, so I also switched control and command.
