As an average knowledge person, it seems like other developers are quickly learning and developing applications with some nice UIs. TAT has some great stuff, but they must really release some of their new concepts, perhaps simply as demos, and make sure that the new BB10 phones are a work of art to differentiate themselves from other developpers, and distinguish the new BB10 software from the others.
You may think this is redundant, you may think this is stupid, but this app seems [to me] similar to TAT work, which is something that I appreciate from Blackberry.
I expect that app to be around long enough to generate a rather sizeable lawsuit from Microsoft. Bill Gates may have killed the Courier project, but they certainly didn't toss out all of the patents. Getting money from a Microsoft millionaire is not likely to equate to a blessing from their patent department....
