Emulsion's is my favorite yet. I really like the navigation menu. I could see an iPhone nano like that if it were around the same size as the LG Chocolate when it is slid open (I used that example because my gf has one and having held it, I know the form factor would still be comfortable to hold). I think texting would still be possible if it was only allowed in landscape mode especially if the text area was limited to around two lines so the buttons wouldn't be too short. With a long thin text area, that would probably still be plenty of space and if not, arrows could be added to the end to scroll up or down to review your text message before sending. In general, I think most functions would need to be orientation specific similar to texting (ex. scrolling through contacts only in portrait orientation). The only thing I would change would be to take out the Safari icon because web browsing on that screen would be impractical.
