I have a Dell Inspiron 1520 laptop. It's been excellent. No down time at all. The only issue I did have was recently (I've owned this laptop for nearly two years). The "H" key started to stick as I typed. I did remove it very carefully and cleared some dust around it ... replaced the key - they pop right off and on again - and it worked great again for a few weeks, then started to stick again. My solution was to use my cordless keyboard which luckily, I already owned. I generally use the setup at home so it's not bothersome to me at all.
