You may have read about my proposed apps:
I'm delighted to report that early versions of both have been built by loyal readers who read the posts and chose to take action.
Meeting Mngr Pro lets you manage timing, share images and connect among many iPads.
Nonlinear lets you import a PDF or PPT file and then jump around. It's not for building slides, it's for navigating them, and even includes a way to drive an external monitor in a clever way.
For ver. 1.0 products, they're both cheap and pretty cool. I have no doubt that with feedback and loyal users, they'll each develop into very cool tools.
