Questions About Cocreate Onespace

My boss has agreed to replace my desktop HP workstation with a laptop/docking station so I can bring my work home and, essentially, work more. Yay? I need recommendations.

My boss has agreed to replace my desktop HP workstation with a laptop/docking station so I can bring my work home and, essentially, work more. Yay? I need recommendations. I am a graphic and industrial designer, and it will be used primarily for Photoshop and Illustrator, with some 3D CAD software such as Pro/E and CoCreate Onespace. The 3D work is pretty small and simple stuff, and nothing that a regular consumer level video card can't handle. It has to be fairly portable - I think a 15.4" is fine. Lots of horsepower and some nice design and features are desired. No brand preference. I would easily go with the Dell XPS M1330 or M1530, but there doesn't seem to be a docking station that is fully compatible with them. What do you recommend?
