I belive that Acer was orginaly an american company, I rember mabey 15 years ago, they made some black moniters for IBM, and they had their own black desktops, just about the first company to offer black computers, they had some quality issues and the american operations went belly up, talking to a service rep when I bought my TM801lci I was told they pulled back to europe and reorginized the company, and were working on restoring american opperations. I couldnt tell you where their current base of operations are.
Dell makes some of the cheapest most poorly built computers on earth IMHO at least, they lost the business account where my mom works after issues with laptops that were very poorly built, and poor support, basicly out of a batch of like 25 laptops 5 of them suffered hinge failure in the first month, that was reparied, within 6 months several of the laptops had suffered hinge failure 3 times, and something like 16 of the orginal 25 had cracked or broken hinges. Dell basicly said it's obviously your fault that these laptops are breaking and we are going to chage you something like $700 each to fix them from now on.
Saying Dell builds the best computers is like saying obviously McDonalds has the best food on earth because more people eat there than any other restruant chain.
