I suspect that the majority of users are not fans of typing in any form. Many of them immediately press the dictation button and tell the phone what they'd like to see. Many people's idea of cool or fun is totally not an office in their pocket, but rather a TV / music player / camera / game console. Plus a phone, of course, for talking by voice.

The target audience of Nokia 9000, people like you or me, are long since not the target audience of flagship smartphones. Bluetooth keyboards, 11" laptops, or some highly custom and expensive hardware are the choices for a proper "mobile office" today.
