Yes, I am also very interested in listing.
Currently, I take pre-printed checklists of the most common birds in my area, that I carry with me in the field and check off which birds I see, then enter them into a computer database when I get back home. It would be nice to just check them off on the iPhone and then e-mail the day's list to myself and import that to the database.
What I would find even more attractive would be the ability to check off, for each bird, the date of first sighting and have the option of calling up a life list right on the iPhone!
Gee, Mitch, you sure have fussy customers!
It is great for us to offer suggestions, but also to appreciate the tremendous range of features -- that actually work! -- in this amazing product. It really is a technological breakthrough that holds the equivalent of many manuals, picture books and videos all in one and all integrated.
More important for Apple, it is a "gateway" product -- like many older users, I had never used the iTunes store before and had never purchased anything from then, in over a year with my iPhone and many more years with my Macs. But after seeing this product in iBird, it was a "must have" and, after seeing how easy and simple it was to buy online, I have now purchased additional apps, music and stuff from the iTunes store, that I had never done before. I also know at least two people who bought the iPhone just for this app (and a few more who say they're thinking about it).
