Do you not think it is about time we had a bog roll dispenser using a clever circuit with latest microprocessor that hands you sheets in your hands as you
bring it under the dispenser, and should also have a digital display to let you know how many sheets have so far been dispensed and how many are remaining, so that you don't get caught short!
oh and a low battery alarm!
You could also give it a voice so that if it has run out of paper, and before you could take your pants down, it should tell you clearly using the speech circuit "Please remember to fill the toilet paper" and there should also be an emergency button to dispense the last 10 sheets in case of a lazy owner forgot to replace empty cartridge of toilet paper.
