Things get a little silly.
Microwave ovens are but on example.
In my case, I look to my first (late 1970's version) microwave oven. It had THREE controls, and I only used two most of the time. The main control was a simple dial for the time to cook. It was nicely logarithmic in nature as the first minute was quite large, but the last one (minute 29/30 as I remember) was quite small.. The second control (rarely used) was the one that controlled the percentage cook intensity (I usually left it at 100%). Lastly the third control was the "GO" button that started the whole thing. Marvelously simple to operate and almost impossible to mess up. Fast forward to today's computerized (the old one used a mechanical timer) user interface. They have all sorts of buttons to control time, delay start, defrost, and which item of food to use, along with an incomprehensible display (which has a segment out in my case). You get to push all sorts of buttons and in a dark kitchen (my wife likes the lights out when se watches TV there) you just can't use the "touch method" to get going. It is a REAL MESS. The problem is that in order to make their product "different/better" a manufacturer needs to have something unique/new and match his competition's bells and whistles. This leads to an never ending spiral of silly functions and people like my mom putting yellow stickums on the "important" controls of the microwave that she needs to use (about three of them).
The lesson here is that fancier and flashier (shinier) isn't always "better". You may have lots of controls for your appliance, but yes, you only select a VERY limited subset for everyday use.
Applications for computers succomb to the same "feature creep", and things like Word or Excel take this to the limit! The software vendor keeps adding features so differentiate the "old" from the "new", I'm sure we have all seen it.
When all else fails, a nice charcoal grill works fine.
