5. Windows 8
5.1. Pros
5.1.1. 1
5.1.1.1. Windows has always had a better file exploring program than OS X.
5.1.2. 2
5.1.2.1. The new task manager, known as Process Manager, is excellent; it gives you a segregated view of apps, background processes, and windows processes.
5.2. Cons
5.2.1. 1
5.2.1.1. Windows 8 will have a longer learning curve for many; the introduction of several new features and their consequent execution will be something of a source of frustration.
5.2.2. 2
5.2.2.1. While this worldwide operating system is far from trash, it is often not as stable as its Mac or Linux counterparts
6. Mac OSX
6.1. Pros
6.1.1. 1
6.1.1.1. Once the user becomes accustomed to the interface OSX is much more efficient.
6.1.2. 2
6.1.2.1. Mac OS X is still the operating system of choice for graphic artists, designers and most others who work with visual and audio media.
6.2. Cons
6.2.1. 1
6.2.1.1. Apple computers simply cost much more than your average PC.
6.2.2. 2
6.2.2.1. While it is true that you rarely hear of a Mac that has gotten a virus, they are not immune. Criminals simply don’t write malicious software for Macs very often. Don’t be taken in with a false sense of security!
7. Linux Ubuntu 12.10
7.1. Pros
7.1.1. 1
7.1.1.1. Implementing Linux on an enterprise level can add up to huge savings: the operating system, and almost all of its available software (including the Microsoft-compatible Libre Office) are 100% free.
7.1.2. 2
7.1.2.1. Linux software is also highly customizable–something that software services can make use of to make a network more secure.
7.2. Cons
7.2.1. 1
7.2.1.1. Its biggest disadvantage is that its end-users and office workers are often scared of it at first.
7.2.2. 2
7.2.2.1. Too many of today's programs run on Windows.
