HP Pavilion Slimline 400 PC Series

We purchased a HP Pavilion Slim line 400 Series desk top. As an older couple our computer needs are simple and we have always bought a computer with a simple system. This computer is the worst we have ever owned. The quality of computers have been going down hill for years. Slow doesn't even fit, the thinking ability of this computer is worse than someone in their 80's. I do not recommend this computer to anyone. And as a note: I don't care much for Windows 8, but that is simply learning something new.
