If you use crouton [1] to manage chroots, you can easily run Sublime and everything else in Linux land. You should be aware of what developer mode is on Chrome OS, though, and all of the negatives that comes with it. The xiwi crouton target allows you to connect to the chroot in a popup window. You can also now launch individual applications giving an integrated experience, including copy/paste.
I ordered the LS pixel, and it was by far the nicest computer I've ever used. I used IntelliJ IDEA in a popup window with zero lag for Java development. After enabling a kernel flag, VirtualBox worked too (with several networking caveats), and thereby Docker.
Ultimately I returned it and got the entry level MBP retina for the same price. Relying on crouton for functionality, meant small stuff would break here or there, much like running Arch Linux. For example, the home, end, page up/page down shortcuts broke in xiwi windows after an update. VirtualBox would cold cut the power to the machine if I enabled bridged networking. 64 GB is exactly half the minimum hd space I need. Developer mode is not a first class citizen within the OS, so I was constantly fighting the machine to get a stable work environment. Etc.
I really really miss it though. Especially the touch screen. It felt like using my future computer today. I needed a dev machine that I could rely on, and my current situation could not justify a $1300 toy. The ecosystem is rapidly evolving, and I am certain I will eventually be using something very much like the Pixel within a couple years. Hope that helps.
