... I've had to invest in Gbyte switchers to get the fast internet on all my machines.
That is a good point. But at only 107Mb/s or so, I can live with the 100Mb/s limitation of my network extenders. Everything else is already 1Gb/s but the signal booster device I use to get a stronger signal to my TV on the other side of the house from my office space is only 100Mb/s. For now that is sufficient, but I will have to remember that the device may need to be replaced eventually.
I really like being able to mark some videos as "Watch Later" and then go watch them on the big screen while I sit in my easy chair. But I have to admit that some of the tutorials I watch don't always keep me awake, because it is a VERY comfortable easy chair and I am getting to the age where a nap just before bedtime isn't a terrible thing.
