Sounds like an ad hoc rationale. The improvements you mentioned for iWeb, iMovie, iCal, and Address Book, as desirable as they are, have little or nothing to do with .Mac features. One might also like to have improved image editing in iPhoto. Since one can make photocasts with iPhoto and .Mac, does that mean that any part of iPhoto is, perforce, a feature of .Mac?
Improved photo editing in iPhoto has nothing to do with .Mac. However, improvements in how iPhoto works with .Mac does improve the usability of .Mac for anyone using that feature. So, yes, it is relevant to this discussion.
There is a lot to .mac and a lot more that can be made of it. Syncing is a feature, Photocasting is a feature. They and other things are touted on the box and on the .Mac feature page . They are as much a feature of .Mac as anything else, and as worthy of discussion as transforming .Mac into a kind of virtual desktop available from various computers, phones, and more.
