Does anyone know if their are any programs or aps that I can download (free downloads, please) for my tablet, which will allow me to type in them, save it, and then upload to my computer later on?

The reason I am asking this, is because I am (attempting to be) a writer, and I often get inspirations for my work while I am away from my computer, and all I have is my tablet, like when I'm on vacation or something, so I'd like to be able to type my ideas down on my tablet, so I don't forget them, and then upload them to my computer (or even have them their so I can copy them, if need be). I don't like to handwrite things, so text is better.

Does anyone know if there is anything?
