That sounds great! Are the highlights editable on your computer after you sync them? Does it take a long time to process the file before syncing? Also, can you sync whole folders, or do you have to open and chose to sync each one?
I use an entourage edge, which I love, except that anytime I want to move a copy with annotations I have to export a flattened copy of it first. I would love to just be able to sync a copy without exporting it first!
