OK, here's a couple novel uses of iPhone.
1) I was at a Red Robin and we saw a photo on the wall from an old Marilyn Monroe movie set. Couldn't think of the movie. Logged on to IMDB and found the title, year, etc. Became a conversation topic during lunch (old movies of hers).
2) Bought some items from sears.com. Received email message with bar codes that needed to be scanned to claim the items at the store. Instead of printing the receipts (I was not at home when the emails arrived) I just took the iPhone and made the emails larger and scanned the barcode right off the screen.
Now that's creative!
