It is very hard to engineer a pleasant experience with new technology. The pain can be eased with usability. Remember that good usability will increase trust of the devices. Also, people will be much more likely to favorably review devices that are usable. There is a hidden usability problem that needs attention.
Many companies think that usability is only about interface design and user testing.
Usability is also about understanding the tasks of users and building technology around them. Most companies first build devices and then test them with users. A much better approach is to understand and define your users' needs and their typical tasks. Then, and only then, should you begin to build the technology. As a general rule, you should not build technology and fit users to that technology.
