Unfortunately, it's not quite the Holy Grail of cross-platform compatibility... at least, not yet. As you'll see in the (sadly vertical) demo below, most iOS apps run at glacially slow pace. They also don't have access to most hardware features, so GPS tracking and other staple features are right out. This is still better than previous efforts, though, and it raises hopes that platform exclusives won't be as important in choosing a mobile device as they have been in the past.

Update: the team tells us that it got GPS working after the paper was published.
