Well we do know that one basketball team uses the Samsung Galaxy Tab 10.1, and this can be a game changer with the right hardware. I may have played basketball, but I am no coach. I have used the app and found it very cool, but it lacking some pretty core features like exporting a play as a video or sharing the play to your team via e-mail or Facebook.
The app takes a bit long to start up which I thought was long for a light to medium application. I did experience when running a video off of the internet, open word document, and two opened Google chrome tabs that I experienced some crashes when I was in the app which makes it seem very unstable. The app is a bit complex for me because in the app screenshots it has the players with names underneath the little circles. Nowhere in the app command bar or the charm setting bar does it have an option for names underneath the players. It works by you (the coach) creates a play step by step and then saves it to the coaches clipboard in a proprietary file format and has a little tile in your clipboard. It says that there is an option to export your file which is nothing, but it only exports it as an XML file not a video file like an AVI or H.264. Truthfully the app is still a bit lacking in terms of speed with nothing open.
The app builds on a nice concept and helps prove the point that Windows 8 can cater to all needs in any profession. I will not let the pre-build argument fly here since basic needs are not met with exporting files and sharing. Also a bigger tile would be nice that displayed your plays and a pin to start menu option would be nice too.
