Status Updates From The Mobile Frontier: A Guid...

"Brainstorming in the wild makes it difficult to ignore the inherent constraints and demands of the mobile context because you are feeling them for yourself instead of projecting and estimating."

"Opportunity cost in the mobile context is not fixed. Instead, it is constantly in flux because it’s based on a combination of need, motivation/urgency, environment, and alternatives—dimensions that are always in flux."

"Don’t waste your time retrofitting old experiences into the new mobile medium."

"When people come out and they show you an iPhone, or an Android, they are showing you larval versions of something much more sophisticated. Both those devices are going to be dead. Deader than hammers, deader than anvils. You can use a hammer and an anvil; those two devices will have no use"

Chapter 4: Nice discussion of environment... not only what it is but how to research user wants and design for those

The three keys to creating a coherent experience are:
1) Identifying the primary use cases for each device.
2)Optimizing the design of each experience to map to those use cases.
3) Maintaining a unified design language (visual and interaction) that scales across a variety of devices.

Chapter 3: Good discussion of mobile context and designing for mobile context.

Ch 2 had some good discussion of where interface has been, where it is, and where it could be going. Not sure I agree that NUI will supplant GUI...
