Every computer I've ever owned has done WAY more than I needed it to do. The same goes for just about every piece of software, every digital camera... you get the picture. Even something as simple as a newspaper has a ton of content that I'm completely uninterested in, but the publisher sells the whole thing to me anyway.
A couple years ago, I paid a little extra for some additional features on a dishwasher, then promptly failed to ever use those features. I knew better but just couldn't help myself.
I think the only electronic gadget I own that doesn't have a bundle of unused features is my 1st generation iPod shuffle, circa 2005. That little musical wonder basically only has one feature - it plays music (either in order or shuffled) and you could get any color you wanted as long as it's white. Side note - the 4th Gen Shuffle now sells for $47 and has more buttons, VoiceOver, playlists and comes in 5 colors.
A while back I read a study that said consumers tend to have a positive view of extra features, even if they are features that'll never get used. That is, when given a choice between two similar cameras, people tend to purchase the one that has a few extra capabilities (and a correspondingly higher price), even though they don't really need to ever (ever ever ever!) use them.
So there's a reason consumer electronics have so many never-to-be-used features: it's what sells. It may not serve the customer well, but it's what the customer wants to pay for. [Sadly, I haven't been able to track down that report - lemme know if you have any more luck.]
When we think we're buying a superior gadget because it's got more features, what we're actually taking home is extra complexity, unused capacity and unnecessary expense. That means the company is selling one thing and we're buying something else. The end result is that we pay extra for stuff that's more complicated than it needs to be and which has features we'll never use. The funny thing is, most of the time what we need is a simpler, more focused capability. That applies to software, computers, electronics and military tech, to name a few.
I mapped it out on the Simplicity Cycle framework below. The sales guy pitches the objet du désir as if it resides in the upper right quadrant but in actual use it's in the upper left quadrant. What the customer needed was in the lower right...
