Cool, but I'd never use them...
I'm generally interested in the intersection of technology, academics, and productivity. Here are a couple of things that have caught my attention, but that I'd probably never use them since I'm lucky enough not to have to take a lot of notes at this point in my life. But if I were a student again, I'd probably give one of these a shot:
1. Livescribe 3 - The newest pen from Livescribe is really groovy in that it connects via bluetooth to an iOS device like an iPad or iPhone and brings in hand-written notes in real time. I've read that the app isn't quite up to snuff yet, but the general idea of it is pretty cool.
2. Evernote/Moleskine Smart Notebook - Here's the "low-tech" approach to getting your handwritten notes onto your device that doesn't require any expensive hardware (if you already have a smartphone). As an Evernote user, anything that pipes content into their awesome app is welcomed.
