@stahtufiang: You can unpin Edge from start and set your defaults to another browser in the Settings app. Right now we don't offer an option to "uninstall" Edge per se.
@sevenacids: We're always investigating options to ship as frequently as possible - moving to Windows as a Service has been a big step forward in that direction, as well as shipping features via our regular servicing updates through WU. We're continuing to explore different options here to make sure the app and platform can be updated at the most appropriate cadence.
Right now, we don't have any plans to bring EdgeHTML to other platforms - we're laser focused on keeping the momentum up on Windows :)
