I don't use HP at all after I owned one computer from them. I manage all the computers at my work and we use Dell desktops and laptops and they have been pretty solid. I use Dell OptiPlex 790 desktop and Latitude E6520 laptop. They both working pretty well. I recently deployed 18 OptiPlex 790 and only one had a power supply problem after a few days of running. I called in and the part of replaced the next day.
