All else being equal, go for the higher resolution screen, and make sure SolidWorks' website in the video card area supports the video card on the laptop. My 3 year old Dell M60 is 1900 pixels and I use every pixel worth of screen size for my small parts. The 1.7 ghz processor is antiquated and I won't upgrade beyond Swks 2006 on it.
Can't recommend brands, since I've used only Dell laptops, but searching prior posts in this group will get you a lot of posts to read for good info. Laptops are OK for smaller assemblies, but I wouldn't want to bet on doing truly large assemblies.
Given that these machines are only 2 ghz, you can figure that you are already starting off a $4000+ 3D CAD program with a limitation by buying the low end of laptop. I would seriously consider getting the faster/fastest laptop CPU, since Swks 2008 is not going to be easy on processing, and you would expect to use the laptop without slowdowns for a couple years (into SWks 2009).
Yes, forgot to say 2GB is a MUST! I like the design, it's thin and looks like a pc that is made for work, not to play. Really nothing to complain. I have 8240 at work and that is also ok, but it's getting old.
