Currently, I am not a customer of c9 and I am a little bit shocked, that an online IDE is not striving to be mobile tablet compatible.
I just signed up to write this: I have a powerful workstation but wish to work from anywhere. I have a powerful IPad Pro 9.7 Tablet which is just great in performance and battery life and perfect for productivity with the iPad Pro smart keyboard.
So I am not sure if c9 is missing the train here, but if you would like to have me as a customer, do your homework and invest two weeks in CSS, HTML and Accessibility mark up so people can use the platform comfortably via keyboard and tablets.
The times that tablets where underpowered web-views is long over and I'd expect that some one is serving the mobile dev gab sooner than later. Be it Diet Coda, Nitrous IDE or you guys.
But forking off such an important aspect of accessibility to the community via an SDK really drove me away to give c9 a try. If I can not use the IDE platform independently, I can simply stick to my workstation?
If I need to, I can than still work relatively comfortable with the IPad via Parallels Access (APP) on my machine or access a server running the gui.
Mobile first guys. Or do you expect people to VNC to their machine to use a Web IDE?
I would like to mobile dev and bring my employees with me. It needs to be easier to have light fun coding in a restaurant without much hassle.
