I can only speak for the US market I guess, but they haven't found a real need for a PC/Mac outside of what a Chromebook can do, so at the end of the day, I don't feel it bodes well for PC/Mac long term.

I'm a developer at work for internal applications (and some external). All of my non-server running things are web applications. They could be accessed by Chromebooks instead of the hp Windows 7 laptops we use now. I doubt we'd switch off PCs due to familiarity at the very least, but we don't need them.
