What's the future of web browsers?
I had a bit of a rant awhile ago about how Edge on Android was making good progress, but desktop Edge still felt like an unfinished, untested and just overall unrefined product.
It's a bit long, but the main killer is the desktop Edge team not being able to make major changes as often as everyone else. Edge is tied to the same 6 months as the core OS, while (say) Chrome has a 6 week development cycle.
