Apple has been doing that for as long as I have been a Mac user - Quicktime 7 -> X, iMovie 11 -> 13, iPhoto -> Photos.app, iWork '11 -> '13, Final Cut Pro 7 -> X ... etc.

They generally seem to have few qualms releasing a reboot that does not have feature parity with its predecessor.

And mac.com -> me.com -> iCloud.com. E.g. me.com had keychain sync and it took them two years or so to bring it back in the form of iCloud Keychain.

One thing that I learned over the years is: let Apple provide the hardware and the OS, but prefer third-party software of proven vendors (Agilebits, Omni Group, etc).

Demolishing Disk Utility or Airport Utility was bad, because of the limited possibility of a 3rd party replacement.

Me.com! I had already almost forgotten about that.

I know that iOS devs hated stuff like Core Data with a passion, but from where I'm sitting, iCloud has been so painless and trouble-free over the years that I have almost forgiven them their earlier attempts at services.

It makes me wonder how Logic Pro has survived this long.
