Yep. Read it with the "One love is all you need" tune. Nope. I haven't become a fan of "Blue". And yep, OneNote is a Microsoft software which does all you need.
For sometime now, I've been cribbing about usability of Microsoft software, particularly once you take into account how much it costs you to own them. I also have a slew of drafts lined up for you, all criticizing various aspects of Microsoft software, from Vista to Visual Studio. I had earlier cribbed about tables in Word - how you have to pre-create them, and you cannot simply tab your way into creating them. I also cribbed about how you cannot mix content the way you like, how you cannot search into content (images) and so on.
Well, OneNote is here. And really, it is all you need. OneNote lets you put text, handwriting, images, music - and here is the differentiator - where ever you want. Really. And It Just Works! In addition, most content is searchable. Even your handwritten text, or printed text in images. And searchable. And it integrates with Outlook. And you can make sections, pages and the like, as you need. And you have a shortcut in Windows that pops it up for you to take notes when your idea ticker starts to work. And you can tag things, make items in OneNote become Outlook reminders, and in short, do everything you need.
