When MS-Windows XP went out of support I upgraded all of my machines to Ubuntu 14.04. Whilst most had been dual-boot, all except one now only run Linux. Two of the few things that I regularly ran under MS-Windows were the odd game and Adobe Photoshop. The games were dealt with by the one computer I left as dual-boot, but Photoshop is a tool that I use often as photography is one of my hobbies. I also wanted to use this on my Linux desktop.
