I have other thoughts about the iPhone as well (e.g., it works great in warmer climates, but in the cold, get ready for your fingers to freeze if you are lost on the winters streets of Boston, New York, Chicago and the like), but this can get you started thinking.

From various conversations, I've learned that working with the Chinese language is always a challenge because it's not structured the same as a western character based language and honestly, outside of our expeirence. It's true – Western designers need to get a crash course in other languages like Chinese, Japanese and Arabic to better understand how input devices (maybe for those languages it's not a keyboard) could be optimized to reflect how people think when they are communicating in those languages (and how the communication is different than western/latin based languages).

Anyway – happy reading and more later!
