It's a shame. What I did is installing VimFX, that is e10s ready, and stick around using for some weeks, trying to reproduce the same workflow I have for years with vimperator.
It's a pain at first, but I got used to it and now I don't have to care if vimperator/pentadactyl will be ported or not.
I often read about happy x220 and x230 users, but the newer x240/x250/x260 are not mentioned as much. Did the build quality decline after Lenovo took over?
