The good use cases are: - drawing (painting), - manual (hand-written) note taking and sketching. - I like Omnigraffle on it, too, and other vectorial drawing. - musical composition both partition editing (with the pencil), and synthesizer/sequencers programming. Also, there's a Logic Pro iOS annex but I've not tried it yet. - and of course, classical tablet media consumption and social, with the added value of multi-tasking. However, I feel that currently applications don't exploit fully the ergonomic potential of tablets and of the pencil. But as a programmer, you should be able to write applications matching your needs and expectations, and notably, integrating an application with user interface parts on both the tablet and the desktop.
