I have laptops that are very convenient but I wanted a desktop because of the ease of typing and using a mouse.  I decided on the Dell OptiPlex because I knew that it was a hardy computer.  It was the computer chosen by the hospital that I worked for and was supplied in every department and nursing station.  The OptiPlex was an outstanding workhorse.  This one (although refurbed) has exceeded my expectations right out of the box.  I thoroughly recommend it for anyone looking for a desktop.  UPDATE:  After a little over a week the hard drive died.  I am unable to get the service tech to get back with so I will probably send it back.  I hope to replace it with another Optiplex.
