Yea, we know what your talking about. You want a car....try a toyota or a honda...j/k.
well...there are several companies -
Dell - everyone here hates dells, but they...well they're 50% of the market for a reason
HP - expensive, but reletivly high qualitity, lotsa options...ocasionally you find a good deal
Apple - free software, very expensive stuff
Alienware - excellent computers...you pay $500 for the name alienware stamped on your comp
Toshiba - I'm not sure if they make desktops, But their laptops are ok
IBM - last time I checked, they only sold laptops. But they sold that division off to a chinese company
Sony - Just like HP and Toshiba
There are many smaller companies out there that make high-end computers that are pretty good, but they're small, and i can't name any of them.
If I forgot any computers brands, tell me. It's a pretty loose list.
What's your price range, what are you going to use it for?
