Microsoft's version does not work on mobile. I have tried many times to make it work on Chrome on Android, but it just isn't designed to work on a small screen and is unusable. It's sad.

When I got out of jail all I had was smartphones I would borrow from friends and the only way I could end up developing sanely was to open a terminal to a Linux box and just use nano instead, which meant no IDE with auto-complete, syntax lookups, formatting and most importantly, debugging.
