    I've been a PC user since about 1986 but this is my first Mac. I've carried an iPhone for years and use an iPad extensively so I thought the transition to a Mac made a lot of sense. I'm still learning the differneces between the operating systems but so far I'm satisfied and looking forward to the transition.

    My 21.5 inch iMac from 2010 was starting to have issues, but after 9 years of faithful service I wasn't too disappointed. Decided to upgrade to this model before the 2010 iMac totally failed and was really blown away by the 4K display. Transferring all my old files and photos was a breeze, hopefully this one will last 9 years as well.

    Love it! Quick and make easier to use! Like the way key board & mouse are charged. No more batteries!! Can read digital small cards by inserting in back of computer and you can buy a digital card reader for the larger cards and attach to back of Mac. So now can read and save my own pictures!! LOVE IT!!!

    I wasn't too alarmed about the hybrid drive as I've had one on a Lenovo Windows machine and it has served me well for several years. My computing needs are largely rudimentary, so it works great. Wanted a Mac as we run iPhones and my wife loves her iPad, The Mac makes easier managing these devices and iCloud.
