What drives me bonkers are the unnecessarily intensely piercing-bright white LEDs, TWO of them, in the UPC scanners at Goodwill, that somehow need to be on a stupid stand so the LEDs shine EXACTLY into people standing in line. Why the hell do you need such obnoxiously bright LEDs to read a barcode? And why do they need to be always on?

And yet, the stupid "modern look" air conditioner I'm saddled with has stupid 7 segment displays that shine through the white plastic shell, and THOSE stupid LEDs have lost 95% of their brightness (in uneven spots) in less than two years...
