Once you get past the HDD to SSD upgrade what is there to be gained from swapping out the old with the new?
CPU performance is adequate for most users already.
Then there is MS saying that Windows 7 won't be supported on the latest Intel CPU's.
A few sticks of RAM here and there and that's taken care of.
So what is left?
How about getting off the MS subscription gravy train?
But that's hard, too hard for many.
So they stick with what they have until it breaks and they can't buy secondhand replacements.
Not a lot to do with BREXIT really but Gartner has to find some neat hook to embiggen their reports that thy charge two arms and a leg for.
