Meet Clibe. The ultimate iPad notebook app. Although I believe nothing will ever replace my Moleskine, this is an app that comes closest of all the ones I’ve tried.
Clibe is a cloud based notebook, meaning that everything you create on your iPad is accessible from your PC as well. But what makes Clibe better than all the other note apps out there is that it allows you to scribble, type and draw very easily. Select the kind of paper you want (blank, ruled or checked), everything is possible. Add to this that you can add pictures from your iPad or imported from Facebook and you have a cool app.
You can also share notebooks with others. Allowing you to easily share your ideas and collaborate.
Summarizing: Go get it. As long as it is still in Beta the app is downloadable for free so be quick!
