But 20 seconds is even easier. When I switched to an SSD in my laptop I saw boot times from drop almost one minute to just about 15 seconds. I no longer dread having to reboot after system updates.

A minute to the desktop is exactly why the tablets are so useful.

If I'm sitting on the couch the instant on nature of my tablet is the main reason I'll reach for that to look at something rather than my laptop.

It's not bad, but spread over X million workers on desktops 5 days a week means a lot of wasted time, and maybe energy.

If 5 million people save 1 minute every day for 200 days a year. Then you have saved 1 minute every day per person, not 5 000 000 * 1 * 200 minutes in total per year.

That kind of math just doesn't work.

Yeah but you don't have to just sit there and twiddle your thumbs while your machine boots. You can just do something else. I'm sure we waste far more time during the day doing other things. We don't necessarily obsess over those types of time inefficiencies. If you wanted to save time you could brush your teeth in the shower etc.
