I think Dell tried too hard too late to get into the gaming industry. When people see "Dell" they see "Business" and "Home" use written all over it. When you hear "Alienware" all that comes to mind is "Gaming Machine".
Great move for Dell, terrible for Alienware. The paper said everything will be seperate but the same was said with Compaq and HP and you see where that went. I give it 2 years and the Alienware brand will integrate somehow with Dell but won't be seperate any longer. It's a waste from a business sense to have 2 of everything.
