Last Autumn I had problems with my laptop (unconnected to Windows 10) and had to put it into PC World to get it fixed. In the course of conversation with the techy I mentioned Windows 10 and
was told in no uncertain terms to stick with Windows 7 as long as I can. Personally I was quite happy with Windows 3, but I suppose if we didn't move with the times we'd still be living in caves and painting ourselves blue.
I also agree with the comment about keeping software engineers in work by forcing us to by re-invented wheels. And as for Apple, I'd rather be tasered in the genitals than use any of their products.
