Nah, you're not old or losing touch--it's just a design thing. If you don't spend time looking at architecture blogs, watching entire documentaries about a single typeface (and know the difference between a typeface and a font), and aren't following at least 20 different graphic designers on instagram--then industrial design/product design is probably just not in your wheelhouse. I think that probably describes about 80-90% of people.
Some of us enjoy a minimal aesthetic where everything that is not essential is removed, and everything essential is immediately available with tactile control. Other people don't care much or they prefer things to be NOT minimal and have bright flashy lights everywhere. Neither is right or wrong of course, just preference.
Plus, little design decisions add up to the overall experience. On the Digitakt, the lights don't blink. They light up, then fade so it is less abrupt and distracting/unpleasant than a simple flashing light. It is a small decision, but those types of small decicions add up to a much better end product and user experience imo.
Compare that to the Aira series of instruments. I know a bunch of people who wouldn't buy anything that looks that way no matter how it sounds. I know other people who bought an Aira (usually more than 1) MOSTLY because of how they look.
Would anyone in this thread choose the MPC Live over the Digitakt based 100% on just the way they look? I wonder.
