I can see the pics just fine.

Figure 3a with the top and bottom slide out which was called "useless" has already been used on previous Nokia phones though the model name escapes me (I seem to remember the one I came across having arabic keys on the keyboard as well as qwerty). The idea is that you would slide out the "wings" and hold it in landscape mode so that your hands would be holding the phone by the wings, giving you the keyboard for use with your thumbs.

Yeah, it's not too great.
