Tablet Usability: Findings from User Research
▻http://www.nngroup.com/articles/tablet-usability
We’ve tested several generations of big and small iPads, as well as many models of Android tablets (including the Kindle Fire) and some Windows tablets (including Microsoft Surface). We found that most websites are fairly usable on tablets and need only limited adjustments to suit this environment. (In contrast, using websites on mobile phones requires many more design changes to accommodate the smaller screens.)
Not surprisingly, when we asked people how they use their tablets, web browsing was universally mentioned as a top activity.
Although tablet-specific applications have plenty of usability flaws, the problems are mainly the same as those that plague traditional application design: difficult features, a mismatch with user workflow, and poor instructions that people don’t read.
