When my computer crashed a few months ago it took me three weeks to replace. Not because of the lead time on a new machine, but instead because I was not sure I needed a desktop or laptop for personal use considering how much I use a tablet and phone. In the end the handful of tasks for which I use a laptop made me get a new one but I realized how my actions have changed based on smart devices and a tablet.
One of the primary things I use the iPad for is consuming news. I have no newspaper subscriptions but enjoy keeping up to date on daily happenings and for me the "Killer App" is Flipboard. The user interface and ease of use make Flipboard the easiest way to consume publications. And the great part about it is that anything with an RSS feed can be read on it, which means 3DEngr is on Flipboard.
To get 3DEngr on Flipboard just click the +Add button in the top left and type in 3DEngr:
