Nikolaj, If you go to PTC's site they will give you an entire list of supported machines to run Pro/Engineer. You can search by Partner or by Product. We have been using Dell M64's, but are in the process of switching to 17inch laptops. This link will get you to this, it might be easier to look by Partner (updated on Feb 22, 2010 for Dell) and then decide which would work best for you. Here is the link to get to this site: http://www.ptc.com/partners/hardware/current/support.htm Dennis
