Stephane,
Yes, and even Dell has ONE model P4 with a legacy serial port, but I have not found any Centrino based PCs with them. Two of my favorite Internet places for notebooks (or desktops) include:
http://www.alienware.com/ (expensive but great) and
[Link: cyberpowersystem.com] (the best bargain on quailty products that you can choose many options on). How about others out there...got your favorite sources for PCs?
I prefer the wireless functionality, size for portability and battery life of the Centrino vs. the gaming graphics of the P4s, plus P4s are on borrowed time so we will all eventually have the problem!
