Thanks to Fred for this info.
Since iTunes version 4.5, it is now possible to place his playlists or iMix on line.
Apple has just rejected for the first time a playlist:

Of course the title was a bit provocative :
One to Tango: Songs with a Masturbation Theme
However, all the tracks were obtained from iTMS...
So now we know that there is a censure system on iTMS too
Hereafter are the results of a xbench test with a Powerbook G4 17'' 1.5 GHz equiped with a 128MB graphic card.

This computer was delivered with MacOSX 10.3.3 Build 7G43.

ethernetworks.de has posted a step-by-step tutorial on how to overclock a 166MHz bus G4 iMac.

THey succeeded in overclocking a 15" 1GHz iMac to 1.25GHz, while a 1.25GHz 17" iMac refused to be overclocked*.
If you try this too, please let us know.
* [trans.: maybe Apple's 17" 1.25GHz iMac is in reality a 1GHz machine that's overclocked ;-)]
Since September and the arrival of the Alubooks, Apple's PowerBook line has been crippled by numerous problems: white spots, overheating... this even deterred some from buying the new laptops. Consequently, we followed with great attention the comments by our readers who received new machines.
It seems like most of the problems are now behind us and that Apple is back to its usual standards. If you encounter any probelm -or are happy with your machine-, please let us know.
