I've got an eMachine at home, we've had for 2 yrs, only issue was a viruis that screwed up the op system. At work we use Dell laptops. In the last 6 months I've personally had a hard drive crash and the keyboard got on another. In talking with a support person he showed me a pile of 25 machines that are busted from the last 2 weeks, and this is for a building that has about 4,000 people. The dells that we get are just terrible, both laptops and desktops.
You'll get better Dell support, but we've had 2 emachines and knock on wood no hardware issues
