What I could really do with on my computer desk is a cup mount, to hold my cups of tea or coffee that I usually have sitting to one side. A cup mount - like you have in your car. You know?
Except that cupmounts, which sound as though they ought to be the same thing, appear to be a different thing. Cupmounts here are things used to protect both electrical and mechanical equipment from impact shock and vibration. Fitting one of these on your computer desk or in your car might be a bit tricky, since they're intended to sustain weights up to 2,800 lbs - which in kilos is quite a lot 1270 or so (or, if you want to get a better idea of what that is, think of the fact that I'm around 70 kilos in weight - that leaves a lot of kilos hanging around doing nothing.)
I'm sure we're all familiar with these kinds of cupmounts, but we probably never notice them because they're so good at doing their jobs and being modest at the same time.
