A few years ago I bought a $3500 laptop directly from Dell. The thing didn't work too well. The screen only had one resolution, which was barely OK. When I complained, the "tech" person asked me not to spread this around. I thought that rather lame. The computer had numerous problems and became unfixable, that is, they wanted the price of a new one to fix this piece of garbage. After the screen stopped working I went out and bought a desktop at a local mom and pop for 1/3 the price of their little gem.
I've worked in numerous Fortune 100 companies that have used Dell with bad results. My currenty employ is stocked with Compaqs which seem to be the choice these days. Personally, I wouldn't buy one of these either. Just bought a Linux box for $800.
Dell. Don't look back.
