I use Evernote for all my note taking purposes. It's one central hub to dump everything I can imagine. It's generous in it's search feature as well as platform availability (there is an Evernote app for it). Even though a lot can be improved in terms of performance and in terms of usability I'm still sticking to Evernote for most of my note taking needs. Having said that I gave SpringPad a shot lately and it's dramatically impressive. It has more feature set than Evernote but the only gripe I had was the inconvenient flow of notes and the performance of their mobile apps. Of course, since I was deep into Evernote I was a bit lazy to move all my notes into SpringPad as well. But if I have to give it a shot I'll go with SpringPad if Evernote continues to lag in terms of performance on their mobile apps.
