Came up with a quick, crude but workable solution for using at a desk or table. Attached edge of scotch type tape to front lip of keyboard and rest of tape (about 7/8" width) to a strip of moleskin. Then clipped writing pen to moleskin just past right edge of keyboard. Weight of pen pulls keyboard forward just enough to be perfectly flat and stable and is completely out of the way. I think for travel you could get by with a super sticky post-it note.

Another super simple solution to the wobble is to sit the opened phone on a folded handkerchief. This is what I've decided to go with.
