I don't have a Vaio laptop but I have 2 Sony Vaio desktops....and I love both of them. One of them is about 4 years old and the other is less than a year. Both kick major ass and I've never had a problem out of either of them.
I went to buy myself a Sony Vaio laptop first of the year to take with me on location when I shoot (to download my digital pictures to while on location) and when I told the salesman what I wanted it for....he said I should check out the Fujitsu laptops. I was blown away with the Fujitsu screen - it has the most beautiful colors, sharp, rich contrast and so....that's what I ended up buying. Some of my buds have seen my laptop and bought them a Fujitsu as well. But I'm sure a Sony Vaio would be a great laptop as well
Good luck,
