I was in the local computer shop to get some parts. They're not one of the big boys but a very small local chain of 3 shops. What they're seeing is Win7 boxes and laptops flying off the shelves and it's been hard keeping up with the demand. They've also been selling PC's, etc. with Linux on them in what they consider "high" numbers. The Win10 stuff is barely moving.
One can still find Win7 at the big guys like Best Buy, but it's something you order and takes a few days for delivery. Nothing Win7 in the stores. I wonder if anyone is actually paying attention to sales numbers and what people want?
