Hi Mike, I recently got one as a test unit from work. We want to see if they work well for light mobility work, not quite intended to replace a powerful workstation, but rather supplement it for somethin easier to take on trips or bring to meetings, etc.
I’m been very impressed with it in overal performance. Spaceclaim runs great with it, but that’s a Direct-X driven video engine, not OpenGL. I only did very light work in Rhino in a couple of heavy models (but small files) and viewport response was very good. I only noticed a weird blocky artifact on screen with object snap drawing new curves. I’ll try to document it. If there’s anything specific I should test please let me know.
The unit I got is the highest spec one, I7 processors and 16GB of ram. Maybe 8GB of ram might be an issue with large files? Especially if you run other programs at the same time?
