You know, as long as you are willing to order from the Apple Store (online or brick-and-mortar), you can get a Powerbook 15". They are still building them, and can deliver them. Of course, this could change, like instantly, but I have seen enough people (physically and in forum-land) get them to convince me the channel is damp, but not yet bone-dry.
I think the 1GHz TiBook is still attractive if you can qualify for the EDU discount (especially if you are willing to wait 4-8 weeks to make an iPod an effective $69), or you can haggle the price down (this is possible, it doesn't hurt to try, at least). If you pay, say, $2200 for a SD 1GHz TiBook, that is still going to be at least $200 less than a new, 1.25GHz if they come out say, on the 16th. And you can flash your firmware to get the SD to 2x speed. Besides the mental anguish of not having the fastest G4 anymore, it is probably a fair tradeoff.
Of course, it helps if you like the looks of the TiBook better than the recycle-able Al. 😉
