I've owned this six weeks.  It's fast, works great, and looks brand new.  I've always bought new from Dell, but, based on other reviews, decided to try this. Good choice!  This model was made back when Dell made sense:  Vents in the back where they can easily cool the machine (instead of underneath), a plug in the back that connects well and stays out of the way, and so on.  It's worth every penny.
