The power jack audio section comes off the main motherboard and is easily replaced if you had to.

The only real annoying thing about the Wallstreets is that if you have a dead PRAM battery and you remove a working battery from the unit for even a second you need to plug in the power brick to get it to work again. Not that big of a deal at home, but it would be a pain out on the go. Then again they units are kind of heavy to be lugging them all over the place anyway. I tend to use mine out on the back yard when I feel like getting some sun.
