Most people don't do heavy video or image editing on their computers anyway. Cloud-based computing is more than sufficient for 90% of those people who do nothing but use Facebook. If you think this form of computing is going nowhere, then you're just as short-sighted as those people who claimed that digital music was a fad.
And Linux is just the damn kernel. Those apps you're whining about are part of a Linux-based desktop environment. They almost certainly will not be included with anything Google offers.
