Power users love things that sync. Synchronization means you can work from any computer and expect the same basic environment. I've gotten hosed by Sync before. I switched OSes not realizing I was also switching to an older version of Chrome. In the process of syncing I lost a few months of bookmarks (it looked like all the bookmarks I had saved with the newer Chrome were gone). So I'm using Xmarks now.
