Toshiba unveiled a new Toshiba Satellite line of laptops with a new feature called the "Sleep and Charge". It is almost so simple that you bang your head: why they didn't come up with this earlier?
The feature allows you to charge your USB powered gadget while your laptop is off. You'll realize the need for this when you're irritated you have to turn your laptop on when you really didn't want to use it, but need to charge your iPod or digital camera.
Let's see if other laptop manufacturers will follow. It is really a must.
