The Unix operating system

Advantage: Virtual Memory

The Unix operating system offers an efficient level of virtual memory. What this means for the user is that you can use a number of programs at the same time using only a modest level of physical memory. The system can handle several programs at once without severely pulling on the system’s resources.

Advantage: Toolbox

This operating system offers a rich collection of small utilities and commands that are designed to carry out specific tasks well rather than being cluttered up with a variety of special but insignificant options. Unix acts as a well-stocked toolbox rather than attempting to do everything at once.

Advantage: Customization

Unix has the ability to string different utilities and commands together in an unlimited number of configurations in order to accomplish a variety of complicated tasks. This operating system is not limited to any pre-configured menus or combinations as most ordinary personal computer systems normally are.

Advantage: Portability

Unix is available for use on a variety of different types of machines, making it one of the most portable operating systems in existence. Unix can be run on both PC and Macintosh computers and many other computing machines as well.

Disadvantage: Interface

The traditional interface for the Unix operating system is command line based, and this command line shell interface may be hostile to the casual user. Unix was developed for use by programmers and serious computer users rather than casual users. A graphical user interface (GUI) is also available, but the traditional Unix interface is command line only.

Disadvantage: Special Commands

Commands required by the command line interface often make use of cryptic naming schemes, and do not give much information to notify a user of what they are doing. Many commands in the Unix interface require the use of special characters. Small, normally insignificant typos can have much greater effects and unexpected results on Unix machines.

Disadvantage: Overwhelming to Novices

While the richness of utilities offered by Unix is a benefit or advantage to many, this may be overwhelming to a novice user. The Unix operating system is not simple by any means, and may be daunting and overwhelming to some users.



mac os


Easy to use

Virus free

With boot camp you can run XP or Vista on your machine, and with Parallels you can run windows programs in OS X


Small software base compared to Windows(with out useing bootcamp/parallels)

Not nearly as customizable

Missing some features that are pretty basic with Windows( my biggest hate is no page up/down key, no real backspace key, and you have to use the control key to right click)

Any more I would say that about any operating system you pick will work, I still prefer Windows Xp over everything, but Linux, OS X, and Windows are all great choices.


Mac os



More Stable

More Dependable

More visually appealing

More user friendly & “just works”

Simplifies a lot of things

Less prone to virus, trojans, etc

Less prone to hardware issues


More pricey

Less control over your computer

Less software options

Less hardware options

Hardware issues are MUCH more severe when happens

More expensive software

My own words about mac

Less Chemicals

More Battery Life
