We are all consumers aren't we? We have opinions and sometimes I think there are some tendencies that manufacturers have that we all hate. Here are a few of mine in hopes that someone reads this and taked it to hear.
Backpacks
The backpack has become a tired thing for the most part. There are some new backs with fancy grommets or solar charging panels or whatever, but they are missing a big thing: MOLLE. The MOLLE webbing system is used for military and civilian gear as a way to attach pouches to belt or other bags for decades. It takes up no space, looks subdued, and allows for a lot modularity in terms of external pouches. Step it up.
Electronics
Stop using glass on the back of phones for the love of christ. No one puts their phone face-down in fear or scratching the sensitive glass, so why in hell would you put glass on the back as well? Are you trying to kill the resale value? I mean come to think of it, that sort of makes sense.
Glossy plastic has got to go. It shows fingerprints worse than stainless steel (more on that later) and scratches in the most hideous ways. Having a matte brushed surface is 10x cooler and doesn't have those problems. Just make the switch.
Appliances
Glossy stainless steel. Unless you are a professional finger print collector, there is no reason for you to have an item which attracts fingerprints like no others. Plus you have to take care that you don't make the surface streaky when you clean it off. This is too much of a hassle.
Washing machines what play a tune when they are done. If I wanted a timer which serenaded me upon completion, I would get one just for that purpose. I get the laundry it done, you don't have to play your stupid little jingle every time. A simple few beeps is far less annoying.
