Re: Still, it seems to be largely a development platform at this stage
Exactly. Lots of comments about "doesn't seem very useful/capable now, does it?" These overlook the fact that most if not all of today's useful tech started out significantly less capable/useful than they are today: automobiles, airplanes, PCs, wireless phones, satellites, etc. This is an early iteration that will almost certainly continue to be developed into ever more useful and capable versions. Given that the current iteration can probably* pour and deliver a cold pint, I'd say it's already fairly useful.
*already has the grippy arm and other grippy arm robots can pour beer so, in theory, SPOT can have that code added.
