Definitely now the "best buy." With a reasonable 133MHz non-DDR 512MB single-dimm/60GB HD/Combo Drive configuration, and no AE, the 1GHz is $1149 ($1091 educational faculty/student).
Upgrade the 80GB HD/SuperDrive (doesn't say what speed that I can find) model to 512MB single-dimm to compete with the new 17" iMac w/512 single-dimm (no AE or Bluetooth on either), and it's $1399 vs $1999 ($1244 vs $1939 educational).
Hardly makes the $600 premium ($695 educational) for the LCD panel and bandwidth-limited DDR of the 17" iMac seem worth it. And definitely obsoletes the rumored to be discontinued 15" iMac.
If you absolutely, positively gotta buy a Mac before the 970s, investing as little as possible in a G4 with one of these makes the most sense to me.
However, now that the bottom-of-the-line Mac has the same computing power as the iMac, and except for level 3 cache, the top of the line PowerBook, and the bottom of the line PowerMac, I have to really rethink my prediction of the 970s not coming until this time next year.
[edit]My earlier post accidentally used "by for your school" prices instead of "buy for yourself." I shouldn't post until after the 2nd cup of coffee.[/edit]
