5. Windows 8
5.1. Pros
5.1.1. 1. The biggest advantage of the Window id that it provides ready-made solutions that can be implemented by just about anyone who's ever used a computer.
5.1.2. 2.Windows 8 has also introduced Xbox Games and Xbox Music as apps that allow you to download games and music from Windows Store, in addition to viewing popular games.
5.2. Cons
5.2.1. 1.Of course, Windows detractors will tell you that there is more need for software services when it comes to Windows. And while this worldwide operating system is far from trash, it is often not as stable as its Mac or Linux counterparts.
5.2.2. 2.The only other major disadvantage of using Windows in the workplace is that over 95% of all viruses and malicious software are written for the Windows OS. This means you have to double-down all security measures if you’re using Microsoft software across the board.
6. Mac OS X
6.1. Pros

6.2. Cons
6.2.1. 1.but it doesn’t offer support for syncing Mac settings like your privacy preferences or which accounts you’ve added to Messages.
6.2.2. 2.The difference here is that OS X offers fewer customization options and those that are there aren’t easy for the average user to change.
7. Linux Ubuntu 12.10
7.1. Pros
7.1.1. 1.Once, you've found what you might be searching for, you can also now do a quick, right-click preview look to see if the file you really want.
7.1.2. 2.While it hasn't gone as far as Google Chromebooks or the Ubuntu-based Peppermint desktop Linux, you can engage with such services as Facebook, Twitter, Last.FM, and Google+ from the desktop.
7.2. Cons
7.2.1. 1. And, probably the most people were upset with Ubuntu's attempt to add Amazon search results by default to Ubuntu searches.
7.2.2. 2.Some people are upset that Ubuntu is actively soliciting donations. Others aren't happy with how Canonical, Ubuntu's parent company, is dealing with Microsoft attempt to block other operating systems from Windows 8 PCs with UEFI (Unified Extensible Firmware Interface) Secure Boot..
