Here are a few reasons why the 12" doesn't have L3.

1. Apple needs to have a distinction between the 12" PB and the 15"/17" models.

2. It's cheaper.

3. The 7445 consumes and dissipates less energy than the 7455. This probably helps compensate for the smaller form factor.

4. It's cheaper.

5. Did I mention that it's cheaper.

6. They took the iBook, slapped a G4 in it, gave it an aluminum case and haven't been able or haven't seen fit to update it any further yet.

They updated the PowerBook 12 to the newest chipset at the very least, and since the chipset in the PowerBook 12 is NOT the same as the one in the PowerBook 17 -- it's real hard to expect them to ever have similar features.

The PowerBook 12 is a lot like a portable iMac, while the PowerBook 17 is more like a portable PowerMac.

PowerBook 12 -- Intrepid IC chipset (new name)

PowerBook 17 -- UN2.x/KeyLargo chipset

[edit -- the 12 matches up well with Apple's published documents and the photo teardowns, 17 has yet to be confirmed]
