Hmm, I think the main priority for UAE should be getting the keyboard working, since that opens up more flexibility in handling other improvements. It's a liiiiiittle slow on my iPhone 4, but not intolerably so. The extra, blank screen space actually works well as a trackpad area so I can play the game without blocking the screen with my fingers. The sound output could be improved as well. I consider these other issues a lower priority, but you and others may disagree
Have you used the iOS version of ScummVM? It requires a jailbreak, but they handle the screen in a pretty neat way. In landscape mode, it's full screen with either direct touch or trackpad cursor input (switchable). In portrait mode, the screen is scaled to half size and a keyboard pops up below. It's small, but it displays the entire screen and allows keyboard input. Something to consider here, maybe.
I will get a glowing review in to the app store ASAP.
