Batteries (included)

I bought a new laptop a couple of weeks ago. With a Vista 64-bit operating system and processor operating at a speed of almost 3 gigabytes, half a terabyte of storage and 4 gigs of ram, it runs cooler and much more efficiently than previous laptops, which allows me to run resource-hogging audio and video software.

Today I bought a 12-cell battery for it, which gives me a full six hours of use per charge. I've never gotten better than two to three before, so it's quite an improvement.

Eventually everything will run on batteries, including vehicles, and they will charge automatically just by setting the appliance near the charger base. (or parking the car in the garage)
