During their work on Multi-Point X, the devs dabbled with multi-touch (http://wearables.unisa.edu.au/mpx/?q=node/147), creating BlobEvents as an extension.
Blob events could be quite useful in harmattan, one such use case is listed here. Given the next device is probably about 2 years out, this hopefully gives some time to get a useful first implementation pushed/co-developed upstream to the X devs.
A conventional pencil has a writing end and an erasing end. The stylus just has a writing end... at the moment. To erase, you have to tell the app that your writing end is now an erasing end manually, though menus or buttons. Because the stylus has a point end and a long, thin line end, it is possible to differentiate between the point end and the line end. With BlobEvents, the sketch pad could notice that the user was using the line end of the stylus and automatically start erasing. So the user just flips the stylus around to write and erase--just like a real pencil.
I'm convinced you creative people here could come up with more ideas (e.g. being able to use a thumb to smudge). Post 'em here! What do you think of
