Apple Mac OS X provides a clean and easy to use interface and is desired by non-Apple hardware users, we have seen Mac OS X themes and total customization packs for Windows allowing users to get the look on their PC's running Microsoft Windows OS. Ubuntu on the other hand, also features a nice user-interface and there exist many Ubuntu customization packs for Windows.
Instead of hacking your way trying to install Apple Mac OS X on PC hardware, how about a totally free, Ubuntu Linux based complete operating system with sleek and user friendly Apple Mac OS X styled user-interface, minus the much debated Ubuntu sponsored search links (Adware) without the unity shell. Welcome to Pear OS 7, an easy to use Ubuntu based Linux distribution which comes pre-configured with free apps and drivers to allow use of your exisitng PC files, printers, cameras and MP3 players. With option to install and use thousands of free applications.
