I use PC at home. Hooked to Dell 27" 2560x1440 screen. PC at least 3 years old with AMD CPU. Yet it does everything I need with no problems.
My office has 11 PC. I don't think notebook will work as a replacement for my home/work needs. Also it is so much cheaper than buying notebook. The oldest office PC has a single core AMD CPU and it is totally adequate for its daily task.
