Most of the time, I run SW on a ThinkPad W500 and it works perfectly for my needs. Totally down with spend hours with my head down, crunching on ideas with this setup.

When I go out to shops though, I would love an ultraportable system I can throw in my bag just to show designs off to people or make a couple of tweaks to a design and fire off a drawing right on site.

I work with very small assemblies and relatively simple parts; I'm not engineering a new aircraft here.

What ultraportable might be able to get the job done for me? I am thinking a ThinkPad X300/X301 would do it, but I don't know.

Anyone have any experiences here?
