Evolution of the Apple Mouse

Playinghte devil's advocate for a moment, Cheaper -> less likely to be econmical to repair, and thus more waste sent to landfill, fewer jobs for repairers. Not _ncessarily_ a good thing. Again, if oyu're not careful, you end up with a machine that makes simple tasks trivial, but which can't be used for difficult tasks (or at least makes htem a lot harder than they should be). Somehting that really annoys me is the lack of a propper command language in many modern window-based OSes. Computeras are good at doing the same thing over and over agian, I should be able to tell them to do that. External heatsinks on hi-fi amplifiers have been around from the tiem of the first transitorised power amplifier :-). The thing is, though, audio amplifiers work at fairly low frequencies. So you can mount the output transistors, etc, directly on the heatsink, and link them to the rest of the components (e.g. by fitting them near the edge of the PCB amd mounting the PCB on an angle bracket fixed ot the heatsink. AMy amplifiers are built that way. But you can't do that with the much higher speed signals goign to a PC's processor or graphics chip or whatever. The pesky speed of light gets in the way. -tony
