Operating System choices

NOTE**Responses to at least two others must be made AFTER Thursday in order for everyone to answer before you choose who to respond to! (You may reply earlier, but at least two must be done Friday - Sunday)

We have discussed a number of different operating systems (Windows, OS X, Linux, iOS, Android, etc.)

What are you personally most familiar with using?

How much of your decision about purchasing a computer is about the functionality/look/feel of the operating system (vs. price, functionality, quality)? Expand on your answer to explain what you like about your favorite OS as compared to others.

Also, compare the issue of look-and-feel of interacting with an OS to the functionality (how you use it vs. what you can do with it) and how that goes into your decision to purchase a particular system. Does familiarity have anything to do with this debate? What are some features of other operating systems that you wish your preferred OS had, but doesn't, or is harder to do
