I currently have an iPad and use PenUltimate as a notetaking app on the iPad and like it a lot. Now I plan to purchase a MacBook Air and I will take this computer with me to meetings and other types of appointments. I'm going to use it for many things but one of the main things I plan to use it for is to take Notes. I understand it's not a touch screen computer but instead of simplly using TextEdit or Word I'd like to know if there's any good notetaking applications for the Mac. I'd like one where I could simply type notes but if possible use the Trackpad or tools to do some minimal drawing in notes and possibly even use the microphone for voice notes. I'd also like the ability to take organize these notes in categories, etc. Is there anything like this available for the Mac?
