I like Dell, mostly great service, but I'd invest in the warranty. It has paid off several times over but every time I needed something they had someone over to fix it the next day at no charge.
And it runs better than other brands I've tried when using other computers.
Long as I remember The rain been coming down. Clouds of Mystery pouring Confusion on the ground. Good men through the ages, Trying to find the sun; And I wonder, Still I wonder, Who'll stop the rain.
