Many years ago now, I had a Palm IIIxe. It's still the best handheld device I've ever owned. Palm invested countless man-hours in making sure that every operation could be performed with a minimum number of clicks and that the Palm's user interface was always zippy. No wading through layers of menus, and no waiting for an application to load. Palm understood that if a user perceived the device as a slow, they wouldn't bother to pull it out in order to take a quick note.
