The best design of a notebook I every have seen was my old Fujitsu. I used it from 2004 until the beginning of the year without any cleaning and any problems with dirt.

I left the BSD Scheduler then on the single core Fujitsu notebook mentioned above but used the new one my desktop machine. It will also depend on the software you are running. Erich
