Owning an Apple product is like owning a Honda product. It will go forever:)
Meh, if you say so...
I haven't even had it a day and I've already run into problems on my Macbook 2.2GHz Core 2 Duo. It seems the internal speakers work just fine for music, but when I plug in headphones or earbuds the centered tracks (mainly vocals) basically go away. And when I plug in a stereo system to the output jack it gives me a loud low frequency hum. This happens both in Leopard and in XP (I have both installed on the mac).
What's weird is, if I go into the system preferences either in XP or Leopard and mess with the left/center/right balance, all the way left or right the vocals come back in (although it's still in both ears, which it shouldn't be), but when you center the balance you lose everything that is centered in the mix (mainly, the vocals and any main instrument that's not panned hard left/right).
I tried updating my drivers, using different headphones/earbuds, wiggling the jack around, different songs and players, even went so far as to reformat and reinstall Leopard. Still messed up

The only aftermarket modifications I've made has been an upgrade from 1GB to 4GB RAM and a boot camp install of XP. Unfortunately, as I'm going to be using this computer mainly for Pro Tools music production and editing, I really need the headphone jack to be at 100%!
I'm gonna take it in to the mac store tomorrow and see what they say... I think I may have gotten a dud soundcard (or headphone jack at the very least!)
