you know how the CD macbook had some problems with the unresponsive trackpad button? and a solution was discovered by resourceful mac users:

i just opened up my macbook c2d (well, just removed the battery), and i noticed that there was a grey thin rubber piece attached to the circular spot where the origami paper went.
nice to know that apple does listen to our minor complaints. although i still would like the macbook trackpad button to be as responsive crisp as the macbook pro. but i guess that is what the extra $300+ or so gets you.
