I beg to differ. Dell is far from useless. They bring affordable computing solutions to just about any home user and at the same time, are able to offer enterprise products backed by industry-leading tech. support. Yeah, we may think a Dell is slow because we run overclocked, custom-built systems but to the average home user, the Dell is plenty adequate because they aren't calculating Pi to 1 million digits. Like beauty, speed is in the eye of the beholder.
I personally wouldn't use a Dell machine for my daily computer. If I didn't know how to build one or how to service one, I'd buy a Dell. If a friend of mine didn't want a system built by me or wanted a 24/7, multi-year warranty, I'd tell them to get a Dell. Dell serves a purpose, just not one that's suited for us enthusiasts.
