From a maker perspective, TE products(they have quite a bit more than I remembered!) still are frontal sketch in not quite Sony style with added depth, leaving something to be desired in manufacturability, durability, and usability. e.g. in this very device, the thin stem of this scroll wheel implies it's actually shaped like LEGO minifig heads, like 中, which doesn't inspire confidence wrt lateral plays. It could easily be made 土 or 王 or even 凸 shaped internally with only the middle part exposed, which not just eliminates play, prevents debris ingress, but also makes areas around wheel edges hidden so quality control around those areas are less of an issue. Or, the shell seen here is shaped like a bathtub with a lid closed at the backside, which means the cross section of the tub has to be ever so slightly tapered towards the front, which affects grip when picking up. And, the backside has no bumps nor there are creases in the side, which further compromises pickup. Or eg the painted wheel. It's going to be PITA to paint. Granted I'm biased feeling always defeated by superb aesthetics of their products - but their design always seems, how do I say, not as deeply connected to engineering ideals just as it is with aesthetics as seen in Sony or Apple products.
