I love Google notebook. They stopped developing it a while ago, but I've been using it a lot anyway. It's my favourite no-frills note taking app in the cloud. I guess now I will have to move to something else.
I would love to use a simple editor which syncs to my Dropbox text files. I've seen some apps which do that but they try too hard to be cool and go overboard with their javascript animations, making them unusably slow. I might write my own.
