At the end of the 'Mephemeris' thread (http://www.internettablettalk.com/fo...ad.php?t=19545) there has been discussion of how neat it would be to use an electronic compass and accelerometer in the context of an astronomy app.

So...what are the chances of ever getting a compass device as well?

Also, is this fancy stuff *only* for the N810, and not the N800?
