Pity you were treated that way, but as I read it, you got one defective computer, and one mis-equipped computer, plus the NAFTA-esque service department (so-called), and a rude customer service rep.
I know this will sound crazy, but if you live in a city, I would recommend you go to a Staples or CompUSA or whatever, and buy a Dell from them. You'll get better service in person and if it is defective out of the box, just box it back up and take it back.
Best of luck.
You know, I almost bought from the stapels guy but all he had were HPs and I have been told to avoid them.
