3 Backlit keys different from non-backlit keys?
I'm interested in upgrading my 2.0GHz to have a backlit keyboard. I know you can replace the entire upper case, but it's rather costly. I've found the backlight panels on eBay for roughly $20 and want to know, are the keys on the non-backlit keyboard going to show through like the backlit keys do on the 2.4GHz model? I've read conflicting information here, one person says you have to replace the keyboard and add the backlit panel, another says you only have to add the backlit panel.
