Guess I'll provide an update since it's been awhile since my OP. I've tried most of the suggestions here, and liked Google Keep and Wunderlist. However their Android app just wasn't what I wanted from it.
I'm a widget kind of guy. I don't like opening full screen apps and waiting for them to load just to quickly check things. And their notification abilities were lacking too.
I ended up finding Any.Do had everything I want. It has an "always there" notification in the drop down notifications area so whenever I get a text or email and look at the notification I see a reminder about the next thing I need to do. It also has a resizable widget so I can easily see the next several coming up, without opening the app. You can make new tasks from either screen too, and supports voice translation. Very sleek look, good web app (no PC app, but easy enough to auto open a website when logging in on windows.
