I think perhaps we have a difference of experience here.

Way back when, when my 386 machine was the newest, hottest thing, between flicking on the power switch (remember those?) and being able to actually use my computer took less time than it took for me to lift my coffee cup to my mouth and take a sip.

There's no computer made today, no matter how much you spend on the hardware, or what you run as software, that gives me that speed on startup. My Mint machine here at home allows me time to take several sips before it even makes it to the point where that Mint logo shows up on a black screen. I can get through about half the cup before I finally have the full screen there and can start working.
