Follow up on my own .Mac syncing problems as of 8/2/06:
With the release of OS 10.4.7, my .Mac syncing woes mostly went away. Bookmarks finally started syncing as intended--about 5 months after I joined and paid for dotmac. Apple graciously granted me extra iDisk space in return for my trouble, which I accepted. However, every now and then something will stop syncing and I'll have to do a reset to get it back. It's not perfect, but I'm happier than when I started with my paid service. As you can see by the article above, I haven't been the only one upset with Apple over dotmac.
