re : speed of the new ^powerbook
the speed equivalence (1,33 ghz = 2.3 ghz P4) is because of the new L2 cache !!!
for the "old" g4 (with L3 cache) you could consider adding 50-60 % so a 1.25 ghz (OLD MODEL WITH L3 CACHE) = approx. 1.9-2.0 ghz P4
so, in theory, and because more L2 cache at full processor speed is BETTER than L3 at ¼ the processor speed the new 1,25 ghz = approx. a 2.2-2.3 ghz P4 ...so adding about a 70-75 % to the speed of the G4 to obtain a good comparison.
Also, these guys had already do some test :

Barefeats also post some test of the 1,25 ghz 15"
