I've owned my Sony for approx. 4 years, and in that time I've seen my sister go thru 3 different HP. and Dell. laptops. This Sony has even hit the floor, and it just keeps giving me perfect performance with quick start up. Sister's Dell hit the floor and the screen cracked and it died instantly! It did take some time for me to delete all the free trial programs that were included, but that was a small inconvenience. The screen is large and vivid. The graphics are beautiful. It was preloaded with IE as the search engine, but I just put Firefox in and it works fantastic with the Vista program that came preloaded on the Vaio. My next computer will definitely be a Sony. Ease of Use Start up was very quick, and with all the diagnostic tools built in to the programming it's easy to fix little software problems Battery Life My battery did die within the first year of ownership, but customer service sent out a new one next day delivery for free and it's been working fine since then Support & Service As I mentioned before, the one time I had need of any type of support they handled it quickly and efficiently. Speed/Performance I'm very happy with the speed and the performance of the Sony Vaio Design I love the keyboard on this computer. It is comfortable on the hands and doesn't make the loud clacking noise that some computer's make when you type on it. Durability This is the most rugged laptop I have ever used.
