I'd be for that too. Also the word NVRAM is kind of missleading, not everyone knows its permanent memory, aka flash, HDD etc... but yeah could have a section for "storage" or something.
In fact how about this:
Hardware
Software
Rather then separate them all. Even then, hardware and software can tie together (Ex: you need drivers so what if a hardware problem turns out to be drivers? then its a software issue)
Of course this would be a major change to what people are use to so I don't see it happening.
