I must say that I'm one customer
very dissatisfied with Dell. I ordered my Planar LCD monitor from them and called to make sure they were in stock. They assured that it was in stock. (This is October 24th)
Then on the site they said that the Planar monitor was out of stock. Customer service claimed over the phone that two or three were still in stock and one would be shipped out to me.
Well, an e-mail then came that there would be no monitors in stock until the 16th of November. The order was canceled.
On November 6th, the monitor comes.
I'm happy I got my monitor, but the fact that they blatantly lied to get money and then didn't cancel the order as requested shows how shoddy of a company Dell is. My high school had a computer lab full of Dells and 3 of the 10 machines died within several months.
About Gateway, back in their earlier days when they still called themselves Gateway 2000, their computers were made so that it would be difficult to tweak your computer with different components than those installed by Gateway. I'd bet their warranty is void if you so much as open the case.
Now don't even get me started on Compaq.
I think the best way to go, if you don't want to build your own computer, is to call a well-reputed computer assembler in your area. Hi-Q used to build computers -- I don't know if they still do. I think that they have several national locations.
I bought my computer from a small company called PCs for Everyone in Cambridge, MA. Although there were a few mix-ups which made me a little unhappy (see my thread about my burned processor), I was at least able to negotiate with them to get my fair repayment for the problems I had. I doubt yelling at Gateway or Dell could make me get my computer back in under a week. Also, they would probably make you send the whole box back as opposed to just the motherboard, processor, and heatsink.
Well, that's my spiel. I'd basically only buy from Dell if I were getting a laptop computer. There's just no alternative to big companies in that area, it seems.
