I recently purchased my first Macbook, so there was a learning curve with the OS. I found the OS to be pretty easy to pick up on (even though I'm sure there are many things I still don't know), so I am very satisfied! I love it so far, and do NOT miss Windows (expecially Windows 8).
Switching from Windows to Mac was the best decision ever. I will not go back to Windows. I switched from the OG iPhone back in the day to android. Also a great choice for me. Apple hasn't done anything in the mobile space to lure me back yet.
When I bought my first Macbook...I actually enjoyed using it.
When the iPhone came out, I had my reservations because I had never had a phone without a physical keyboard before, but about 2min. after getting it out of the box and getting it fired up, I knew the situation was exactly the same.
moved from a blackberry curve (didn't like the direction they were going in 2010) when iphone came to verizon i picked one up & haven't looked back since....got the 1st ipad mini in 2012 & once my acer died (after only 4 yrs!) i bought a 2013 mac air.
From a self built Windows PC desktop to a MacBook Air: Absolutely satifisfied, especially since gaming on a computer is no longer a priority for me. The user experience is great, I just use it without having to constantly do "maintenance" on the OS.
From a BlackBerry PlayBook to an iPad: Again, satisfied. There are a few things I miss from the PlayBook, but overall the iPad just fits what I expect out of a tablet better.
