Beat me to it
The point was really that at one time, the PC was synonymous with IBM (ie the "IBM PC") or "IBM Compatible". Today, they are no longer in the PC business at all.
As for the venerable SM58, I don't see how anyone that has done a serious listening and usage comparison in a live sound environment could believe that an SM58 is not an inferior sounding microphone than say an EV ND767a. I also found that the ND767a is much better at keeping feedback under control than an SM58. With 3 open microphones on stage, I got around 6db more volume before feedback with the ND767a than the SM58..... and actually that isn't even completely the case since the fact was that with IEM's, I can peg our system clear out to full volume with the ND767a and not get any feedback ...... this is not the case if I put SM58's on stage.
Perhaps someone here has a different experience than I have?
