In addition to my current Windows 7 laptop, I have three old laptops which are still functioning. A Windows 7, an XP, and an old DOS laptop I bought in 1990. Still works!
The older Windows 7 is my travel laptop, since it's less valuable if stolen or lost.
The XP is useful, because it's the only one that can access my old emails when I used Compuserve's email program. Although I haven't opened my XP in a few years.
The DOS laptop brings back memories of my youth.
I plan to buy a new laptop within a year. I'm planning a dual boot, with Windows 10 and Linux Mint Cinnamon.
I tun win 7 on the other side of this dual boot with Kubuntu being my everyday OS. I don’t get on the web with the win 7 side. There’s just a couple of programs I use now and again that I’m just used to.
