it's ok because I currently have a 3-year old 2.4 GHz P4 desktop and no cpu 
problem :)

moreover, it looks like 64 bit is not always the best choice today, and the 
mobile version of the P4 doesn't look good for audio processing (see the 
discussions about the denormal problem in the pd mailing list, for example)

ok, so I was wrong and the AMD equivalent to the pentium M is the Turion, but 
it's a 64 bit processor, and it looks wiser to setup a 32 bit system currently, 
especially because I will use it with both linux and windows for audio.

well, I have a shuttle desktop and it's ok :) but a M/Turion laptop is better 
for this of course

thanks for your information,
