A s many of you know, I built a house a little over 3 years ago and wired it to the hilt. I thought I had my future-proof bases well covered, but 3 years is a lifetime in today's techie world. When we first moved in there, my sons were 12 and 8 years old. They liked music to some degree, but since it wasn't a prioirty for them, I didn't bother to wire their rooms for speakers. Fast forward: My kids are now veterans in using iPods, iPod touches, and the Sonos wireless multiroom music system. It's no surprise, then, that my iTunes bill is through the roof.
