I bought an eMachine 8-10 years ago and it was the worst computer I've had; that was back when computers came with Windows ME.

The eMachines is the only computer I've had anywhere that has out-and-out failed me. Normally I get a new computer if my husband gets one; I get one a year later or something since it's not "fair" that he have a new one and I don't, LOL.
