Well, as Drobo's focus is security and usability and not speed, who this is not a good match for is people who are often transferring extremely large chunks of data, such as video professionals; my friend shoots on a RED and the USB interface of the Drobo takes it out of consideration.
Usability is not high priority and these tools currently do not allow the data to be processed without manual intervention.
Regarding the techniques themselves, the study's principal finding is that usability is not a secondary characteristic of persuasion i.e., it is not something that designers should consider after designing for persuasive effect.
Unexpectedly, objective differences in aesthetics or usability did not affect learners' emotional states.
However model uncertainty and unknown and time-varying communication delay can make the system unstable or badly affects its usability if not properly managed.
In summary, this paper states that usability can not only be defined scientifically under a coherent, unified framework, it can also be measured objectively and systematically.
The philosophy is that usability should not be an add-on, but that everyday processes should be modified to be user-centered.
Usability is not only about measuring how people use a product but more importantly, it is about exploring the relationship between how designers have intended their products to be used and how users interpret these designs.
The current version of our prototype has no graphical user interface because usability was not in the scope of our work.
