The fact that everything bolts together inside like a ThinkPad and there's no glue means it's highly repairable. I've been looking at getting one as well, they're almost too good, I'm worried apple will revert to gluing things together as they're user repairable, which means they ought to last nearly forever. I've been eyeballing one as well, I would prefer the higher end air or pro but being able to take the whole thing apart with a single screwdriver is very appealing.
