When you use your computer(s), do you tend to do something all the time, every time?
I, for example, tend to tap this area of my laptop with my thumbs, sometimes really hard, too. Dunno why I do it, I just tap it.

I also tend to scratch my MX518s "middle area". After two years of that, it's left a little mark:

I also have an urge to keep my MX518 and G11 super clean. And I tend to scratch the sides of my G11s buttons.
This is propably another "Only our Freezer..."-kind of threads.

The idea of any hi-fi system is to reproduce the source material as faithfully as possible, and to deliberately add distortion to everything you hear (due to amplifier deficiencies) because it sounds 'nice' is simply not high fidelity. If that is what you want to hear then there is no problem with that, but by adding so much additional material (by way of harmonics and intermodulation) you have a tailored sound system, not a hi-fi. - Rod Elliot, ESP
