This is my third refurbished laptop...like a good used car,if taken care of,it will last a long time..The Dell D520 with Windows 7 installed was a bonus.I bought this for my wife who needs are simple.I also bought this for its former use as a business computer .Having had it for over a month it works wonderfully.If you are not it need of of the latest bells and whistles,a refurbished is something to take a look at...Check that its done by a microsoft certified co.and that the certificate of authenticity is with it..good buy.
