No-click Mouse?
TheRealZappa writes "For quite a while now I have been looking for a mouse that would not make any "clicking" sound when the buttons are pressed... Does it even exist? So to all you quiet-pc amateurs and hardware hackers... Can it be hacked? Can it be bought somewhere?" Sure it exists, I think they call it a "trackball" or "touchpad". Seriously, I've never had a non-broken mouse that didn't click.
just break the catch that clicks under the mouse buttons, i've done that a few times on accident, pulling up the buttons(nervous habit). you lose some tactile response, but i don't see how to get around that, smooth motion is usually what is quiet.
You may still be able to get a Cirque 'glide-pad' touchpad for a mouse - while it has buttons, you can use a tap on the pad as a click, and re-assign the buttons to different actions (such as cut and paste). Under Windows, the drivers provide the 'click' throught the PC squeaker - but this can be turned off.
I haven't seen any for sale for a few years now, though. (On the other hand, I have several, and NONE of them have failed in years of every day use - though the touch surfaces are all well polished and slightly concave now. They're the most reliable mouse I've ever encountered.)

Sanity is a highly overrated commodity.
I seem to recall that Mouse Systems made simlar mice for other systems as well, including Macs and PCs, so you may have some luck finding an old Mouse Systems mouse with clickless buttons that will work with a relativly modern computer.
There are also a couple of PS/2 style mice from IBM that have silent buttons: both the standard wedge shaped PS/2 mouse (Model 6450350) and the Psersonal System/2® Mini-Mouse (Part No. 95F5443) have silent buttons, and can easily be used on any modern PC with a PS/2 mouse port. Both of these mice are simple opto-mechanical two button jobs, so anyone needing a multi-button or scroll-wheel fix is SOL.
Finally we have the early Microsoft Serial Mouse (FCC ID: C3K7PN 9939) with a 25-pin serial connector and buttons that curved over the front edge of the mouse. This mouse also had clickless buttons. Upon disassembly one finds that the buttons are simple dome microswitches, which must mean that you can get such microswitches in both clickfull and clickless versions. Again, this is a simple opto-mechanical two-button mouse.
