Unfortunately, Motorola makes truly despicable user interfaces for their products. I'm a sysadmin and it took me quite a while to figure out the startac cellphone interface. My pager (the big old clunky alphanumeric pager, not my shiny new alphanumeric pager or my sanyo cellphone) had icons that made no sense. Even my new pager from them isn't that great: the green button sometimes means yes and sometimes no; the red button sometimes means yes and sometimes means no. It's not consistent enough to be simple, and it's not powerful enough to justify any sort of complexity.
