The problem is that marketing and sales types are often much closer to upper mamagement types who make the decisions than the lowly engineers who make all of the ideas actually function. And at the level that those folks run at, style does trump substance, and they get huge salaries no matter what. So who listens to the engineers? They are always saying that things are a bad idea.

I believe you're right, William K. The problem is that all that "product differentiation" results in more confusion and, ultimately, dissatisfaction with the product. I just don't get it.

Charles, you are right, but that concept is exactly the opposite of what the marketing group is demanding, which is "product differentiation", which often means all sorts of features and functions added to things that really do not add much value for most of the users. So the push needs to be on the marketing people, and "good luck with that".

William K, I'll repeat what I said somewhere else on this site. If all designers of electronic products looked at the toys made by Fisher-Price, we'd have a much simpler world. And a better one, too. Knobs and big buttons. Nothing extraneous. That's all I ask for.

Yes,Charles, there is a reason but it may not be an adequate excuse. At some point somce concession should be made to user convenience, which, BY THE WAY, is not the same as adding hundreds of features that noboy will ever think of a reason to consider using. How about the FF and rev buttons, which on a VCR only have one function, but on a dvd player the same button jumps to the next section if pushed and released, but it serves as a "fast" mode if pressed and held. Isn't that counterintuitive?

Thanks, William K. I'm glad to hear there was some method to the madness.

Charles, actuyally, with only two controls it should not be hard to keep track of them. Besides that, the power button is between the deck and the enclosure side, keeping the switched lines away from all of the other electronics, which are noise sensitive. So there is a valid technical reason for why the button is where it is. Probably the AC power connection is on that end of the enclosure as well.

Stories like this always make me wondr if these manufacturers ever do any human factors studies before they release their products. I can't imagine they do. As William K pointed out in an earlier comment, you get what you pay for.

That makes plenty of sense, 3Drob. I have an inexpensive unit with stop/play, eject and power on the panel. All I ever use on the panel is the eject button to put the DVD in or take it out. The eject button turns the unit off or on. I too, use the remote for all other functions. It works just fine.
