Dear aikiboy
I've had Macintoshs for many years, and at my age, need something simple. While Mac are devastating complex inside, they are the simplest computers to use IMHO. Currently, I'm using a 2015 27" iMac and it's wonderful. The screen is 5K and there's 32G memory (more can be added) installed so it's great for editing photos and using Photoshop or Lightroom.
Of course, as with everything new to us, there's the unavoidable learning curve. To ease that pain, there's great free tutorials on YouTube or by subscriptions like Lynda.com or KelbyOne.com or dozens more.
The screen is bright, response is quick and if you're close to an Apple store, free classes are yours.
One of the things that has sold me on Apple products is the free online and phone support. The phone support is unmatched, the response is very professional, polite, very informed.
If you live close to me, I'd demonstrate its photo editing on my iMac (I also have an 2009 and 2011 21-inch iMacs that I've discontinued using-- want one?)
This posting is my first on UglyHedgeHog so I'm sure it's full of mistakes. As mentioned, everything has a learning curve! Hope some of this helps!
