I have wouldn't buy another laptop unless it had the same complete care coverage as what Dell provides.
I have had three mother boards replaced. I travel a lot. My office is in La., I have had one mother board replaced at my office (spilled coffee). One motherboard replaced while I was on a project in Santiago, Chile, and another just replaced when I was on a project in Pa., The technician came to my hotel room to replace it.
Like said I wouldn't buy another brand of laptop unless it had the same type of coverage.
Complete care coverage is well worth the money!
