Eliminating all those post its

I was looking for an app to substitute all my post its and the papers where I put down my todos or the ideas/stuff to think about. Mainly work related. I wanted a simple app that does synchronize between iPad and iPhone, so I am independent when and where to capture an item for the list. This app is similar to the already installed one from Apple, but simpler. I personally dont need to put due dates etc to my to do items. I need to quickly jot them in the list, sect those I would like to focus on today, leave the rest for the next day or even later.
So, just a great app. What I could imagine as a further development would be to allow for multiple lists to select from. For example work and private items etc. More features would make it more complex and be on the cost of its simplicity. Those that need more features (e.g. Colors, priority symbols, etc.) should go for a different app.
