tbh sony have been trading on their name for a while now..... but i wouldnt use dell either, ive gotten through many many many laptops in the last 4 or 5 years, Ive found Toshiba to be the best for service and support, i had a clogged fan causing overheating and noise, so i called them up just before the warranty ran out, they collected it, cleaned it up, gave it a general check and delivered it back to my door within 7 days free of charge
very top service.
HP/Compaq are good at supporting their older models, back in 2005 i wanted some info relating to a 2000 model machine, very out of warranty, they sent me an email with a complete service manual attached :bannana:
dont even get me started on "Acer".....
however a good company to look at are "ASUS" i use their components in my desktop builds and find the stuff to be top notch, all their gear comes with 3 or more years warranty, friends relative bought one of their laptops on my recommendation bout a year ago, i visitted recently and the machine was still running perfectly, they hadn't had any issues at all.
Samsung - got an NC10 netbook back in february, cant praise it enough incredibly useful, fantastic battery, still very usable out'n about.
Friend had a samsung laptop, very usable machine he gave it to his brother when he bought a new machine, short while later the brother had broken the power connector internally, had to open it up and solder the cable to the motherboard (a new connector was too much hassle) was very impressed with the neat layout, very tidy and well thought out (some machines are a nightmare to work in) so again a good company to look at
to recap
Sony acer dell - personally not fans
ASUS, Toshiba Samsung - excellent machines in my experience
