Hands down if you're wanting a technological solution, an XP or Windows 7 convertable tablet (you want a real keyboard, and a proper digitizing pen) with OneNote. Yes it's proprietary and evil, but it's the best new thing that MS has release in 10 years.
You can record the lecture, while taking notes, and the notes get linked to the time durng the lecture. You can search the audio recording!
You can import all sorts of file formats and annotate them as you go. Those you can't directly import you can print into Onenote and then annotate. Imported images are OCR'd behind the scenes so you can search them.
Typing and handwriting work together. You can either convert your handwriting to text, or leave it as is, but still search it.
Note the emphasis on searching - you can in one shot search text, handwriting, audio, and images for a keyword. The last three use fuzzy algorithms - when it OCR's an image, it doesn't OCR it to an exact text, but rather to a set of possible texts, all of which are searched. Likewise for audio and handwriting.
All that shit goes right out the window when you have hundreds of millions that believe WWIII will bring back their spiritual leader that will magically lay the enemy to waste and give them control of the planet.
Unfortunately for the world, there is also a good number of batshit crazy Christians who believe the same thing.
9/11 wouldn't happen today in a world where the assumption is that when a place is hijacked, everyone is going to die. At the time, the standard assumption was that the hijackers just wanted money and would land the plane somewhere, and everyone would go free after the negotiations, provided no one tried to act the hero.
After 9/11, that's no longer the default assumption. When you add in the extra cockpit security, hijacking a plane to crash somewhere is no longer an easy way to do a lot of damage. Putting billions of dollars into protecting against one, very specific and unlikely to succeed, avenue of terror is a misuse of security funds. Given the ease of hundreds of other avenues of terror, we're far better off investing in intellegence.
