A while ago, a co-worker asked me to critique pictures of a couple dozen laptop bag designs. His wife's marketing firm was looking for feedback before moving from designs on paper to prototypes. Incidentally, all it takes to be a design authority is hip glasses, a T-shirt that says "helvetica" and using "Photoshop" as a verb.
I spent the last few days playing around with three prototypes. I found the features I like now wouldn't have been on my radar 2 years ago. Magnetic and velcro closures are much easier for me to use than buttons, zippers or snaps.
In fact, most of my purchasing decisions are now made based on function over style. Don't get me wrong, I'm still dapper as hell. I just pay closer attention to things like how the lid to my coffee cup opens or the zipper on a jacket.
As such, I will now offer my services as a gimpy product tester to all industrial designers. I'm sure this will become a full time job. My blog is insanely popular amongst the Auto-CAD set. Priority will be given to those designing ergonomic beer bottles, coffee cups, cutlery, sports car transmissions and large-screen TVs.
