I put my Model M back on my work rig since I don't want anything to happen to my Evolution (it was expensive, and they don't make them anymore, don't cha know?) while I am in and out of work for vacation during the holidays, and I forgot how incredibly loud the Evolution was in comparison. The noise level in the office must have dropped about 50dB since I switched back. The Evolution will still be in use at home, and is certainly going to stay in use, and, as a matter of fact, I am looking to add another to the family in a few weeks. While my Evolution is on Xmas vacation, I will probably try to do a little surgery to it to see if there is any way I can dampen the noise (even I appreciate the massive reduction in noise switching back to the M) and remove the programming chip to keep it from spazzing out (this gets annoying after awhile). I might be abusing a Dell AT101W for a few weeks, too, for sh*ts and grins, but, for now, it's back to the M. Thanks for listening and for your thoughts and concerns. Group hug time.
...Or not.
