An idea a day: 80. Use mobile phone as a ultimate remote control. There are in the market many kind of all-in-1 remote control which could take over all the controls for your home appliances, eg. TV, DVD, computer, air conditioner, projectors, etc.
If we could have mobile phones which can act as a control, then it should be the most convenient appliances.
People easily lost their remote control, but as cellphone is a proximate gadget, we could find it and use it easily.
This cellphone control may not be only used at home, it could also be used at office/ school, it could act as a powerpoint presentation controller, letting you to do transition of slides back and fore, without touching the computer.
Mobile phone has transmission technology other than infra red, electronic appliances could match with them and update the controlling method, like using bluetooth/ Radio Freq, in this way, the control need not to be facing the receiver directly, and the distance of control could be much longer.
In addition, manufacturer could save $$ on control by not producing them, just let people to use their personal phone for controlling, it could release burden on their marginal margins.
