Personally, I stopped trying to find an app to do all of that. I put my notes in gmail drafts and try to keep them at a minimum, put my appoints in google calendar, and use short-lived bookmarks. I painfully found out some time ago that I don't need much more than that - I try not to have lots of reminders/todos/etc.

If I had to do that, I would try to do it on the web instead of using a dedicated app. If you really need all of that well I guess you're stuck :)
