The main quirk is that it appears to have some form of digital tourette's.
It barks, randomly. I have no idea what causes it to do this. It just barks.
And if frequently makes the IM sound for AIM, but I rarely have anyone speak to me there.
So my laptop dings and barks randomly.
Plus, I still have the iPod/printer wireless issue despite the help I was given. The fixes I have been given last a couple of hours at best.
