I understand, I really do. It just not what I'm used to and, from a more functional viewpoint, it doesn't make as much since to me.

First and foremost, it is a phone, and that is it's most important task. To facilitate that, from my viewpoint, you basically need an "on-hook" and "off-hook" button.

What I''m used to is...
Green (off-hook) - I'd prefer this go to a dialpad, but can get used to it going to a searchable contacts list.
Red (on-hook) - End calls, and doubles as a end (or minimize in the WM world) applications.

To add any additional features to either button just complicates things, and can cause it to behave in ways I do not expect. Hitting the End Button to go to Today isn't a problem; however, it's tendency to turn off the display whether or not I'm already there is a problem (applications still opening, during open dialogs, etc.). Plus (and this may be the bigger issue), since it functionally "ends a call", I have no way to manually turn off the display off while talking. That means, I'm going to use another button to blank the screen anyway, so why have to buttons assigned to the same task? This is especially true when I'm already used to the display-off being a side button.

In the end, it's just a personal preference thing.
