I don't normally have a strong opinion one way or another about specific brands, but since you mentioned HP, and are looking for opinions, I feel the need to reply.
I have an HP Laptop (dv6119us). I have really liked the design of the laptop, and the specs have served me well. However, I will never buy another HP product again
no matter what. And it is all due to their lack of customer service. My laptop has a defective GPU which causes it to overheat and cause other components in the computer to fail. After confirming through HP's website that my computer was in fact defective and getting extensive information from http://hplies.com/index.php
about this issue, I called them for support. I called directly to their upper support personnel, who confirmed that they had indeed sold me a defective product. But they absolutely refused to fix it at no cost despite the fact that they had won a settlement against nvidia to cover the costs of repairs of these defective laptops.
I spent countless hours and months fighting them over it after reading numerous stories from other people in the same boat who had actually gotten the free repair after significant time and effort. I never had any luck, and the computer continued to go downhill until it was unusable.
To make matters worse, the computers that they did "fix" were no better off. HP replaced the motherboards in these computers with the same defective parts, then gave a 90 day warranty knowing full well that the GPU would overheat and cause more catastrophic failures in the near future, but most likely not until after the 90 day warranty expired.
So, the lesson learned? HP does not care at all about its customers.
In fact, my service rep flat out told me they didn't care if I never bought another product from them again. I don't know about you, but I don't think that's any way to do business...
