I agree with itimpi - reading list will work well for this.
Another way that I use: create a text multiple column. Choose a value for each device. When you connect a device, search for onDevice:true and use bulk edit to add the tag to every book. Then search for onDevice:false and remove the tag from every book.
Reading list simplifies this a bit by letting you clear a list then add all selected book to the list.
