Go with Dell and pay for the extended warranty, 3 years or so. Dell is really great in terms of support, warranty and replacement!
If you have a Dell store at a mall nearby, take a look at the notebooks and choose a model you like. You have to base your decision on your needs. I personally wouldn't buy a big, bulky wide screen notebook if I am to be carrying it around. Not too powerful either because it would kill the battery very fast and it would overheat or have a very loud and annoying fan spinning all the time.
Base it on your needs!
