I'm hanging back for now. Why? After reading TidBits' article, it appears that neither of our Macs, which are running 10.6.8, will be able to see my iPhone's content, we won't be able to backup to the Mac or easily exchange photos.
My major backup resource now is iCloud, so maybe it's not important. Do folks have some thoughts or experience with doing this.
Of course, one answer would be for us to just get a newer Mac...but that wouldn't be the cowboy way!
