This particular login screen has changed a couple of times, but the idea is the same.
You can choose to Launch the Ipad or the small device version and either way you will see about the same information, however it is presented in a way that will fit better on small mobile devices or an ipad/ desktop computer.
Both views will work on any Internet connected device, you can check them both out and see what works for you!
The Ipad/large screen does show more information regarding the calendar though. Feel free to check them both out!
