Hi guys! I have a 1st Gen Macbook (White). Anyways, a few months ago, the edge of the palmrest closest to me, where my right wrist lays, started to crack... Then, several weeks ago, my clicker below my trackpad started making a very loud "CLICK" (lol... obviously) sound. It's actually a bit distracting when in the library or something. Also, it seems a little less responsive then it's supposed to be. And now, the area below my left wrist is beginning to crack. So, my first question is: If I take my computer to the Apple store (I do not have Applecare, just fyi), how much will they charge me to replace the palm rests? AND: Is a new "clicker" part of a "palmrests package?" And would getting it replaced likely reduce the "clicking" problem? Thanks!
