The fact that the links says nothing about power or memory management worries me.

Those two things IMO were major things affecting webOS. Pretty much all the phone devices shipped with insufficient memory.

And given that Fx OS is JS, HTML etc. based, those things have a tendency to chew up a fair bit of mem. Throw in a JIT and suddenly you are in a mem swap situation (which is definitely not batt friendly).

So, yeah I would like to see more docs about how those are going to be addressed.
