Here's a direct comparison between the 12" 1.5ghz g4 powerbook and the new Mac Book. As can be pretty clearly seen, the Mac Book is really a significant step up- given that the g4 is more than two years old at this point and has a single processor, one ought to expect this, but the difference between the two machines is pretty impressive. In many cases the difference is more than double.
I ran these tests just after login. Quicksilver and Dragthing were running on both. Hopefully neither tried to sync during the tests. Oh mysql and apache were also probably running at the same time.
The heat is the major question on the Mac Book. While I've yet to see any posts about the thermal past on it, it feels hotter than the memory of the first 867mhz g4 12" that I had.
Check out the stats of the Mac Book running Rossetta. It still manages to keep the lead on the G4.
