Do you honestly think OS kernels are the most relevant (or even very relevant) security issue we are dealing with? I'm not an expert, but seems to me that just about all newsworthy security issues (that aren't about hardware) are not kernel related. Personally I'm mostly worried about stuff that will happily run with user privileges, e.g. inside a browser or email client.
