I have commuter bikes with 1x11, 2x11 and 3x9. Each has its advantages and disadvantages. There are many good reasons to go with a 1x setup: less weight, simpler shifting and lower cost not having to get a FD, shifter and extra chainring(s). 1x11 is new to me, and so far works great. Not saying it will work well for everyone, but for a relatively flat commute with lots of little hills or stop and go, it could be perfect.
