I love techtoys. My VCR lists all the recordings I made on it and what date/time I recorded them or the title of the show (or the one just before it because the broadcasters are so stupid with the schedules)
En mass they seem to be haphazzard with their choice of design features and sometimes they have constraints of time &/or firmware size which means the proceedure to discombooberate the frazzle fiddle is about as meaningful as that.
AND the manual is something else, even when written by someone with english as a first language.
Try looking at these as an engineer/programmer, when you know they could have done a better job just by thinking a week longer. Frustration, they could give me a job helping them, I am waiting for their call (or job ads).
eg
My home phone (if I paid for it) could handle caller ID with names from the personal directory not numbers. But the 20 long list of redial numbers is still only numbers. Now is that sloopy thinking or what? AND it wasn't cheap - but digital. It wasn't as if they didn't have competitors &/or established practice to compare with either.
