Have the Asus Windows All in one with the iMac in comparison a little bit tested. The Windows All in One PS's are mitlerweile no bad devices more. This must be said already. The touch screen provides for me but no added value there. I do not sit at the computer and pressing around the screen. Since you have always a dirty screen and somehow fits a touchscreen only to a tablet. (My personal opinion). To put it briefly: I have chosen for the migration from Win to Mac and regretted it for a minute. The Mac runs extremely smoothly and almost silently. Incredibly good performance and a better display than in Mac I have not yet seen. Just buy it from me !!!
