interesting post on a wide-ranging iPad usability study by UX guru Jakob Nielsen. Unsurprisingly I guess, it is the wild west again (circa 1993) where users can click on anything and have different things occur. Sigh…
iPad apps are inconsistent and have low feature discoverability, with frequent user errors due to accidental gestures. An overly strong print metaphor and weird interaction styles cause further usability problems.
"It looks like a giant iPhone," is the first thing users say when asked to test an iPad. (Their second comment? "Wow, it's heavy.")
The full 93-page usability report is here.
