MobileMe was just the wrong time to roll it out. Absolutely have NOTHING to do with the iPhone. Its great how you can take everything wrong and blame it on the iPhone.
I suspect that the original "push back" of Leopard was due to the fact that there are a few key individuals that understand the core of OS X and they were needed full time (100 hours a week and lovin' it) to assure the successful launch of the iPhone.
There were several side benefits to that effort:
1) experience gained in supporting variants of a core OS on multiple platforms
2) enhancements to XCode and IB in general
3) development of a Simulator
4) new/enhanced testing/debugging tools
5) began re-implementation of OBjective C frameworks, e.g UIKit (the way they should have been done, originally)
These benefits are being fed back into OS X!
Add to this the infrastructure to sell and distribute apps through the App Store.
Likely, OS X has regained the lost 6 months many times over... a pretty good ROI.
