The Eden UI
The Eden UI
Sadly, what we've mentioned so far are but minor irritants compared to the main problem of the unit: the Eden UI. While Notion Ink has put in a significant amount of work to turn the Android 2.2 based tablet into one that feels just right for a tablet, the Eden UI is not without its flaws. It's sometimes slow and unresponsive, and in the span of two days of usage with the Adam tablet, we encountered multiple Force Closes (i.e. crashes) that left us gnashing our teeth.
Given the more than capable NVIDIA Tegra 2 hardware, we found the unit turning extremely sluggish when we started having multiple windows (Notion Ink calls them panels) open, and swiping them back and forth is a sluggish experience best left alone. The user interface also has a steep learning curve even for normal Android users. For example, you'll need to read the manual before you can even get started, which is really silly given that most devices these days aim to be as simple and intuitive to use as possible.
While the above mentioned problems were still tolerable somewhat, it's the actual apps inside that left us with an overwhelming urge to shake our fists at the sky and maybe punch some walls. Launching the Facebook app started out fine, but upon entering our credentials, we got launched to a browser app to re-enter said credentials, which then loaded the Facebook page on the browser instead of the panel app. We had to search online for a workaround before we got the app to work.
The normal Android notification bar also blocks out the Eden UI, and unless you've read the manual, you probably would have to do more online searching before you find out that tapping on the top left corner where the battery icon is will hide the bar. It wasn't really obvious to us, so a novice user would probably have even more problems with the interface.
