I have used a Dell desktop PC now for close to 4 years, perfect machine....
Bought the machine back in Holland, had 3 year warranty with 24/7 service.
Once got a major virus (Mc Affee expired....) here in Singapore, called the Dell helpdesk, they checked and found out my PC warranty was not worldwide... One would expect that it would end there, but they offered me to service anyway. 2 hours later I got a new 180Gb harddisk for free, a new subscription for Mac Afee added to it and I was up and running again. For free...
A friend of mine is also always cursing Dell, but I looove them.

And Bremen, I think Dell indeed has a perfect and sharp purchasing power. But not just focussing on the cheapest available, definitely also the best components for the best price, it's a combination.
Adn when spending a few billions a year on R&D, I would think they do not just simply assemble any components to build machines...
AMD versus Intel, always the same battle....
I am an ex-Inteller, so be careful....
