Because I had nothing better to do today at work, I took all the letters and punctuation off an iBook keyboard I had lying around. I also used the tab, caps lock, return, etc. just so I could have the 3 rows completely white.
Theres actually a few benefits to doing this:
The ENTIRE key now glows when I turn on the keyboard light- it looks way cool!
For some reason these keys seem to be giving me a little more tactile feedback.
