I'm planning to buy a new Dell desktop. I'm using Windows 7 and quite happy with it. I just want another for a backup. I'm not too big on changes and may opt for another Windows 7. But between Ubuntu Linux and Windows 10, which do you prefer and why?
Suggest getting another exactly the same as what you have already. That way if your rig craps out you can plug the drive into the other machine and be running again in no time.
As for "what to buy today"? All seems up in the air until Intel gets the Meltdown/Spectre business under control.
