I'm very excited about this! I recently switched to desktop + iPad, and I can't currently code at all on the iPad because all the apps I tried suck. I'm hoping that VS Online will solve my problem.
This is absolutely a problem we hope to solve :) We’ll be adding “official” support for Safari on iPad soon, so stay tuned, and please don’t hesitate to reach out to let us know any feedback/questions you may have.
