Look at it this way, $30 per machine is a helluva lot cheaper than mitigating whatever 11 will break.
Not to say don't update, but Enterprise works on this stuff in advance, testing their systems with the newest versions as their Betas are released, to develop their mitigation strategies (including staged deployments).
Even there, $30 is cheap insurance if they need a little extra time to address issues.
For the home user, fuck that. Just ensure your security model includes layers, e.g. Don't run as admin, isolate systems that are at risk, etc.
Hell, at home I run different VLANS for my own stuff (cause I do risky things), one for TV (because those things are terrible about security), another one for everyone else, and a guest network.
