@drmikenyc well said & I agree with you 100%
I am actually a media person, a photojournalist, and yes, I use iPhoto.
I do so for a number of reasons. Firstly all that you said above, it's a great photo library management tool that as a bonus has some reasonably powerful yet simple editing tools.
As images are a part of what I do not the core of what I do I need simple, efficient & effective. Not cumbersome with steep learning curves etc.
The other side of it is that all of my clients like to do their own tweaking.
I can tell you for a fact that most major magazine publishers (here in Australia at least) generally the first thing their art dept will do when they receive images from photographers is to undo most of the PhotoShop changes the snappers spent hours making.
So why waste time when it's better spent elsewhere?
Anyway... it is tragic to see what Apple has done to iPhoto.
When they cancelled iPhoto & Aperture I think the big hope was that we'd get something somewhere in the middle. An iPhoto Pro. All the elegance & simplicity with powerful options there if you needed them.
But no.
We got an app that's like an iOS app ported to the desktop. No other way to describe it.
I just find it bizarre that most other app developers are trying to find ways to make more amazing, more fully functioning apps for mobile devices, trying to take the desktop experience to mobile.
Yet Apple seems to be going exactly the opposite way. Trying to take the mobile experience to the desktop.
And really those that are virtually flaming posters with 'move on or move out' type comments... Really? I mean... really?!?
Recognise that not everyone does things your way & that some people actually rely on functionality to do real work things.
Remember that the experience of one is not the experience of all.
Apple as a platform has always been a magnet for those wanting to do things differently. Now it's succumbed to tragically linear thinking so totally opposed to where it came from. And no. This isn't growth & evolution. It's going backwards.
For what it's worth I spoke with Apple support a couple of times about Photos & how retrograde it is. They said they have had a lot of negative feedback and told me that if they get enough feedback in support of iPhoto they may well consider resurrecting it.
