Here are just "some" reasons why Dell's suck if there is any question about it;
-They're tech support that the customer is ultimately paying for is worse than 3rd party free tech support. My friend who bought a Dell comes to me for help, and I'm just a newbie.
-The case is proprietary. They make very nice cases, but try putting another motherboard in it. Suppose yours dies giving you the opportunity to upgrade for the same price as replacement... ooops... sorry... you can't put another mobo in it! They'd be better off building cheap cases if they're not gonna make them upgradeable.
-Poor Sales/ delivery; I've heard of computers being left in the back of trucks, orders cancelled without notifying customer, half hour + waits to speak to someone about an existing order.
The market leader is not always best. Amiga kicked IBM's ass at making computers, but Amiga didn't advertise. IBM was simply the leader in marketing. Creative sucks, but they probably still lead sales in sound cards just because they set the standard in computer audio 200 years ago. Market share has nothing to do with how good a company is. Take AT&T for example. They'll call you up, get you to switch over to thier service by lying to you, bill you for things you didn't want, make you have to talk to someone after a 1 hour wait that doesn't even speak english well just so you can cancel thier service! Hey,... if you want to go with industry leaders... be my guest
