Frustration ! I had no trouble installing win8 on my main pc ,which is relatively new. Apart from a few tweaks it is running very well. I would not consider going back to win7. Operating it with a mouse is no problem and after a while becomes quite natural. However, on my two year old laptop it has been a different story. I could get it to run but after four attempts of trying to sort out various things not working correctly I gave up and reinstalled win7.No doubt if I had persevered it would have been ok but quite frankly I don't have the time ,inclination or patience to mess about any longer. Shame really because I like win8 but will probably give it another go sometime later when I have time to spare.
