Actually, if I'm not mistaken ksplice already is completely free and open source. They operate kind of like Red Hat--what you're paying for is support. From what I can tell though, there's one crucial difference--ksplice can't function without support. Now in either case you are free to provide your own support, but I think the task of providing ksplice patches is just nontrivial enough (due to the nature of the problem, not ksplice's design), that the economies here significantly favor everyone paying one company to do it, rather than anyone trying to do it themselves.
Not to diminish the achievement, but haven't they built him a redundant right hand?
Why throw hardware at a software problem?

Now, don't jump down my throat just yet. Yes, I realize these are not for most people, but your "minimize" idea reminded me of dwm and xmonad's default tiling behavior. While replacing standard window managers with things like dwm and xmonad wouldn't be acceptable, perhaps standard window managers should be extended with faculties that allow easy tiling when desired. Supplying this particular need with hardware seems... silly.
On the other hand, given that the extra screens are touchscreens there are other advantages. I would not object to my laptop being a giant DS, but I'm a sucker fo gimmicks.

Although, I did have the same initial reaction. I think the term "nanobee" is just far too distractingly catchy.
