The week of the Keynote, there were TiBooks available at the Apple Store in the Mall of America (Bloomington, MN).
I asked a lot of questions about discounts for those and the older 12" and 17" machines, and I may not be remembering it right, but I think it was:
$100 for the 12" models when the new ones came in
$200 for the TiBook
I don't recall the 17", I wasn't as interested in those. Hope that helps.
