for this you really don't want chrome and android to converge... I mean you still might, but I don't think it's what you think it's going to be like...
That would be bad in the same way windows RT is bad.... software compatibility. But it's the exact opposite situation of windows rt vs windows xp/7/8 architecture wise.
Developers are getting in the habit of writing x86 compatable builds for apps in android that use the NDK (assembly, c++, etc), some retro console emulators for example have both armv7 and x86 builds bundled together in the same apk, but for the vast majority, as of right now, only a small fraction of the "really good" software on arm android is available on x86 android. I don't see this changing anytime soon.
One thing that would be smart ..... and I'm going out on a very long limb... so far that I am probably beyond my own bounds of what some may consider "reality" lol, but maybe, just maybe, build an arm emulator inside of android for these x86 machines... so they can properly run apps written for arm.... I'm not sure if you would have to actually run a full build of android inside of android or not, or if you could just do like a compatibility layer similar to wine but instead of libraries it would be architecture... not even sure if something like that would be feasible, but if it was... then it would open the door on full total convergence of the two at least on x86 hardware running this chrome/android hybrid monstrosity.
that... or just port chomeos to like a transformer or other arm based laptop and converge away.
