Let's see You spent $520 to upgrade the software on a 3 year old outdated computer. I just checked the Dell site and you can but a OptiPlex 790 Desktop for $489. A poor way to spend your money in my opinion. If others spend $520 to upgrade their 3 year old computers then Staples will be up 19% very soon. Staples made much more money on your upgrade than they would have made had you purchased a new computer.
