MAC

My use of computers has been very limited until a few years ago.  I could pretty much do only what was shown to me. My fear was that I would push a button and tear the thing up, or at least mess something up. After I overcame my fear and learned to explore, I was amazed at the vast resources that were available on the actual PC and on the web. I was only familiar with Windows until my work purchased one MAC and I was the winner. After a month or so, I could at least type a document and navigate my way around. Just as I was getting comfortable with the MAC the IT guy came and converted the MAC into a dual system, and now I am a Windows user again.
My husband is a huge Ubuntu fan. He has installed it on all of our computers and laptops at home, as well as, any family who will allow. I was not familiar with Ubuntu nor had I heard of it until I met him.
Upon exploring the MAC tutorials, I realized that I have forgotten all that I had learned.  I first viewed the stacks. Stacks are folders in the dock which contains lots of items, such as applications, documents and downloads. If you have a folder that you want to become a stack you just drag the folder to the right side of the dock. When you want to quit, you hit command Q. I also learned that if  the command key is held down while the tab key is pressed,  a strip will appear in the center with all the applications that are open. The third thing I learned is that Preview is MAC's graphic viewer and PDF viewer.
Overall I find the MAC very user friendly. I would consider having one for home and personal use if they did not cost so much.
