C3D2009 runs faster on the desktop, but is quite usable on the laptop.....my actual work time is probably split 60-40 between the 2 computers. I prefer the laptop display, just becasue it is so crisp! 1920x1200 on a 17" widescreen vs 1680x1050 on a 24"widescreen. That, and the fact I can sit in my comfy chair at home & watch some sports while I'm I'm working is another plus.
