So I ran Update Manager. Against "New Ubuntu release '14.04.3 LTS' is 
available", I clicked "Upgrade". Resulting in the following warning. So 
I clicked "No".

{Your graphics hardware may not be fully supported in Ubuntu 14.04.

Running the 'unity' desktop environment is not fully supported by your 
graphics hardware. You will maybe end up in a very slow environment 
after the upgrade. Our advice is to keep the LTS version for now. For 
more information see 
https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D Do you 
still want to continue with the upgrade?}

I visited the recommended site. Which said the following. Being true, as 
my PC is an old hand-me-down!

{While llvmpipe is pretty good on modern CPUs, if your video card is old 
your CPU is likely old too, and it may result in unusable performance.}

After which I noted the following.

{Alternatives may include sticking with an old ubuntu release or 
switching to one of the lighter weight derivatives or Debian. For 12.04 
and 12.10, ubuntu-classic (no effects) is also a feasible option. To do 
this, install the gnome-session-fallback package, and then on the login 
screen click the gear icon and select "Ubuntu-classic (no effects)".}

What do you advise?

I am beginning to think that it may be time to get a more modern PC. 
Which as a pensioner I had avoided for budgetary reasons!
