I have no qualms about Alienware.
What junk. Friend of mine had a Area51 desktop. What a PoS and rip off to boot. I built him a replacement machine with spare parts I had lying around. He was so impressed with the improvement. His video cards kept dying inside his Alienware because their shit (and ugly) cases have horrendous airflow. They wanted to charge him $2000 to fix it. ya right.
I have a Dell laptop for work. I am very happy with it. To my surprise the only bloatware that came with it was McAfee. That was easy to uninstall. I have a sweet 9-cell battery with it too that gives me 4 hours. I doubt gaming would be any good on it though with standard Intel graphics.
