Even in-browser consoles have been done for a long time. At least Digital Ocean and Ubiquity Hosting have... how else do you fix a broken firewall rule that blocks SSH or something?
Linode has had a textmode in-browser console for quite some time (LISH). This post is introducing GLISH:

Oh yea, I mean Linode's had the out-of-band in-browser console since at least 2009 when I first became a customer. Are DO and Ubiquity's consoles graphical, too? If that's the case then I agree this is catching up, not innovation.
Ubiquity's did, although I never had a reason to run a GUI on any of my DO instances -- however I don't see why they wouldn't -- all these "graphical" consoles just use VNC to project the GUI into the browser.
I suspect there hasn't been much demand for Linode to integrate a full graphical console, but it's been on their checklist for some time and are now getting around to it. Could be a sign of polishing up the platform, which I'm sure is good for all Linode users in general.
