I'd say you want to upgrade to 10 while the new laptop is under warranty. The 8 is a dead end, and Microsoft will want to wash them out of circulation as quickly as possible. You will have to move off of 8 - to 10 or to Linux, your choice.
Of course make a complete backup before you upgrade.
I very much appreciate the advice. As an elderly math major, I admit to Luddite tendencies, and ignorance IS bliss...most of the time. p.s. I hate computers and cell phones, yet here I am. :{)
