I got my desktop iMac a few years ago when I went full-time online and I chose 21.5" over the 27" because I thought the bigger model was “overkill” for what I was doing. I didn’t mind the monitor size but I wish I had of upgraded just for the internal storage and processing speed (which my dad tried to get me to do because he knows computers). At the time, I did some video editing and graphic design work in addition to storing a lot of files on my computer. However, I ended up getting a laptop at the start of the year and I have not used my desktop once since then. I had to get used to the trackpad, but without it I couldn’t enjoy working while traveling and, of course, swaying in the hammock. Writing (my primary focus now) is pretty portable, otherwise I would probably have to be confined to a desktop computer’s functionalities and space. 😄 I guess I’m the complete opposite! I purchased the Macbook Pro last year and it just sat in my office motionless. I got rid of It and now planning on going for the 27. I mainly prefer larger screens. My phone is the largest model currently available as well. I just cherish the space.
