I'm curious why you didn't wait until Photos is out? What if it's a great Aperture replacement?
Perhaps this will help. Its a recap of my last few years using a suite of iPhoto on a media server (mini), Aperture and iPhoto for iOS. As I have a headless server, I need solid power management and remote management so a mini, iMac and MBA all ran 10.6.
Circa 2010 Apple releases iPhoto with a new library incompatible with "old" iPhoto. No problem, don't update.
Need support for Fuji XTrans. Nope, not available. Use Lightroom for 2 years.
XTrans support available, not for 10.6. At the time I was a virgin and updated to 10.8. 1), iPhoto libraries now incompatible and either share (not a good approach as that means my desktop needs to be on all the time) or maintain 2 different libraries. 2), Little did I know at the time of the consequences for power management and remote management. Lots of time spent updating all three machines to 10.8, debugging, change the server back to 10.6 and live with the consequences of different flavors of iPhoto.
Running Aperture 3.4.x on the iMac and notice white balance temp/tint is wacko. Oh, its broken. Need to update to 3.5. Need to update to Mavericks. Another OS upgrade for a simple app.
Update to 3.5.1, more library in compatibilities. No recall what they were. Something to do with the unified library perhaps.
Adopt iPhoto for iOS. Lousy editor but nice features with Journals and Slideshows. Put the time into learning them and building a series of web journals.
Now, per the iOS 8 release notes to developers, iPhoto won't run, neither the Journals nor Slideshows will migrate.
Aperture now being discontinued. Search for a replacement or wait for Photos?
I frankly don't need this sort of nonsense. I'd rather be out clicking the shutter than sitting in front of a computer doing OS updates, sorting out sharing and remote management and juggling photo libraries. So I will take a pass on waiting for Photos. If the developer notes re iPhoto for iOS is any indication, I don't expect a painless migration from Aperture DAM to Photos. So I'm out of Apple photography apps. Probably what Apple wanted as I am not their target group.
I have 30 years with Apple and like their hardware and OS on both the Mac and iOS side. But I do not plan on getting locked into yet more turmoil with their, so far, disjointed and poorly thought out long-term plans, or lack thereof.
And iCloud to bind all this together. So far in 2 years Apple has managed to wipe out all my Journals photos on iCloud twice. The pages, text, links to photos, etc still exist but the Photos are gone as in reflected in lower usage on my account. Which I pay for. DropBox has never let me down. And it can already easily do what Apple has attempted to do with PhotoStream/iCloud. Plus, DropBox works with all apps for desktop Mac's and just about all the apps I use in iOS, except those from Apple.
I will certainly continue to purchase Apple hardware. But my future software strategy will revolve around stable development and using DropBox to tie them all together. Which probably means a lot of other Apple software will be uninstalled or banished to the "Junk" folder I keep on iOS devices.
