Maybe the AMD E-Series processors have improved a little, but my experience with them a couple of years ago was AWFUL! I wouldn't touch a computer with an E-Series processor. I had a customer with a brand new (right out of the box) All-in-One PC that had an E-1 Series processor, and it took more than 10 minutes to boot until I removed the Norton antivirus that came with it. Even then, it still took nearly 5 minutes to boot and be usable. I hope that they've improved some in the last couple of years, but I wouldn't recommend one to my worst enemy.
[VMod comment: AMD's E2 processors are significantly faster than the older E1 processors, so yes, they have improved.]
