Thought i would steal some thunder and start this thread. I have a new android phone and found this free app that is GREAT for keeping/organizing notes. Its called Evernote. Allows you to take notes, organize them into notebooks and even allows speech to text that works pretty well. You can take screenshots/clip pics/diagram and tables off the web and attach them to notes. Also you can take a screenshot or what not and from your photo gallery choose the apps icon in the corner to add a note to the caption.
Cheers
