A very good question parasight, by getting rid of all interface options and making a lot of the control gesture based it actually becomes quite do-able. Of course there will always be the issue of a small screen, but that is a trade off of having it on a phone or MID. And having it on a phone or MID has been requested a fair bit in the past. And I for one would *love* to have SL running on the road using TMO's super fast 3.5G connection.
