Why do you say Google will "never fix" the "lack of apps"? What do you call adding support for running Android apps? Clearly they are working on addressing this, even if they're not there yet.
Of course, I'm happy for Google to prove me wrong. I would have firmly thrown Photoshop into that category until Adobe announced they were making a ChromeOS-compatible version of it. I happen to quite like my Pixel, so if the Chrome Apps can one day let me do everything I need to do without needing to go to a Linux chroot, I'd be thrilled. Until then, however, I need Sublime (Caret is pretty good, though), I need git, etc.
I believe the Eclipse folks think that Orion (http://www.eclipse.org/orion/) is the path out of that jam. I'm super stoked about that project, and think it may have real legs if they don't lose focus.
That is their solution to your git need, also, unless one requires a dedicated git client to do rebases or other ninjary: https://github.com/creationix/js-git
I am 100% positive it will take some mental and maybe even logistical reorganization to switch to a cloud-based coding environment. Almost every change I can think of in a professional capacity is evaluated in a cost-benefit analysis.
But today I am home sick, and thus have no access to my properly configured PyCharm, nor access to the local feature branches on my machine and it would be a bunch of ssh hoop jumping to deploy anything that I did write while at home. My interests are pretty much in descending order of that list. I would love a copy of cloud-PyCharm.
So the idea, and if I recall correctly, proof of concept, of ChromeOS running Android apps isn't a large stretch.
edit: I just watched the promotional video, and I was right about their interest in ChromeOS running Android apps, I was just wrong about its maturity level. The video states that ChromeOS runs "select" Android apps.
