I went ahead and bought from Dell, as well. I've never had a Dell in the past, so this will be my first experience with them. I've always owned HP's in the past, and granted they have always been great machines, to my standards.
But, IMO Dell has just about everything I wanted. And I'm not the type of person to go with the best; I've always stayed at a medium level.
To me, buying a computer is no different than purchasing a car, considering I work for an auto manufacturer. For instance, if someone lives for owning a H2 or Land Rover, then there's no way possible they would "stoop down" to the Mazda level. Respect is given over a period of time, and hopefully Dell will truly shine for me, in the end.
