I used a Dell Inspiron , and it was either a Dell or a MAC for their killer warranties,but since it was my first computer, 4 years ago,I went with Dell and their complete care warranty.
Nothing wrong to say about them, one time I put my feet on the screen by accident and 3 days later it was back at my place, like a new one, no hassle and without costing me anything, that was also like 2 weeks before the end of the warranty lol
So my next laptop will be a Dell for sure.
