A good example are "stemless wine glasses". Uh, WTF, you moron, the stem is there for a reason. You just made it look trashy and made it much worse. Oh yes, I want finger prints on my wine glass. Yes, I love to warm up my wine when I hold it. Oh yes, I don't want to be able to hold it up to the light properly.
(Classic designs are not always right though. I really don't see the point to double hung sash windows. Why in the fuck do I need to be able to open the top part? When do you want the top sash open and the bottom closed that you couldn't just have the bottom open instead? In my experience with these fuckers, the only thing the top sash is good for is letting in massive air leaks, or falling down slightly and getting stuck and being incredibly hard to slide back up because it has no handles or anything.)
And now for a photo tour of horrible designs around my home :
Pushing a window open with my hand was much too difficult. It only took a second and was easily adjustable, but I had to lean over. I'd much rather crank on this fucking floppy handle for five minutes. The result is that sometimes I want the window open but I just can't be bothered to take the time to crank it a million times, so I just open another window that isn't on a "convenient" crank.
These kind of faucets are horrible in many ways. The mode clicker at the end is always flakey (this one happens to work mostly), the fucking retractable head is totally unnecessary and just makes it wobbly and lower flow, but worse of all is the fucking joystick water control. It makes precisely setting the flow volume and temperature almost impossible. The variant of the joystick which pervades cheap hotel showers is the real pinnacle of shitty water control design. Fucking hot/cold knobs worked great. They're easy to adjust precisely, they hold their position and can't be easily bumped into scalding or freezing, they aren't fighting gravity so they don't slip. If you really want to change it would could do flow & temperature knobs, but don't fucking abandon the two-knob design! Knobs are perfect! I think water control peaked when the two faucets for hot and cold got combined into one faucet, but you still had the two knobs, it's been down-hill ever since.
I've done this one before, but it was in my sight so let's do it again. The Melitta single cup dripper is such a clear case of taking a near-perfect product that does the task it is designed for, and just fucking it up for no reason. (the only thing I would change about the original single cup dripper is I'd make it a bit bigger, because I like to use an obscene unreasonable amount of grounds for one cup of coffee).
Product designer : Why would anyone want to grab a drawer handle from above? I know, let's seal off the top and make a big surface to get dirty!
Quick - find the Stop button. Too late, your burrito exploded. Thank god for the "vegetable" feature. I'm sure glad there's a "hold warm" and "light timer" feature. And WTF is "cook" ? I bet they could cram some more buttons on there and it would be even more deluxe.
You could do the stop button test again. Think about how much your hand has to move around the panel just to set it to bake at 350. There's just no fucking thought about usability. Touch pads like this in general are just horrible interface devices, and sadly are getting more and more common (see for example washer/dryer rant). Two knobs is the perfect interface for an oven. One for temperature and one for function (off/bake/broil) (physical radio buttons would also be okay for function).
WTF are you product designers thinking? Do you actually think you're doing good work? You're not. You're making shit worse. You should be ashamed. You should feel humiliated and miserable every day at work as you take good products and make them trendy or "modernize" them or make them slightly cheaper to mass produce.
There needs to be something like a hippocratic oath for product designers ; "First, don't make it worse".
