I had switched over to Linux last year for the same concern of Win 10 reaching end of support. I wanted to switch over while I still had time to switch back (even if temporarily) of something went wrong.
I’d highly suggest start dual-booting or load Linux on an older system to get used to using it as a daily driver now rather than waiting until you don’t have the same choice.
I fully understand the issues with the logistics. I get that the delivery people are often held to unreasonable standards and forced to insane expectations of quotas.
But, when there are 3 cars in the driveway, the lights are on in the house, and it’s the middle of the afternoon, it is absolutely the delivery person’s responsibility if they don’t even knock. They don’t even need to stick around more than 5 seconds, at least actually make the attempt.
