Have you ever got a drink on a hot day filled with lots of ice to keep it cool. But when you try and drink it the ice gets in the way of drinking it as quick as you want to. My idea is to put the ice in the glass first and add a plastic filter into the glass to trap the ice at the bottom and then pour the drink in. This is really simple but it would hold the ice at the bottom of the glass keeping the drink cool, and it would not get in the way of you drinking it.

Tired of waiting on hold? Put them on hold instead. Activate the hold holder and it will repeat a message "You have been placed on hold. Please press five and I will pick up the phone. You have been..." etc. So when the guy who put you on hold presses 5, your phone rings, and you pick it up. For an ironic twist, you could play music for the guy who put you on hold.

Wouldn't it be cool if you could click the button on your house key and the door would unlock and lock, like on a car? Wouldn't it be cool if you could push down a button and your windows would open (like on a car)?

Create desktop wallpaper for computers programmable to any time zone and which has the sun rising on one side and setting on the other. The desktop landcape could be chosen to suit the user - cityscape, beachside and so on - and the shadows made by trees, cars and buildings would create the illusion of being outdoors.

Manufacture light bulbs with a fragrant coating which is activated by the heat each time the light is switched on.

Provide broadband packages where the connection speed is set at, say, 1mbps. Then if a user needs to download a particularly large file they would be able - at a click - to boost their connection to 2mbps for an extra fee per minute.
