> because it can be lower-level a little moot if the core is still C just like in Singularity. Not exactly, as it's more likely they didn't want to roll their own kernel when there's a perfectly good open source one. Microsoft and Windows didn't really have that luxury and based on the project's likely goals with its commericial leaning successor, Midori, they wouldn't want to use something under the GPL either. I'm not a hard core kernel developer, but I'd wager one could be written in Vala if one was so inclined.
