I need a decent ipad text editor and don't know where to begin looking (I'm a total ipad noob). It need only be a basic editor for rough work. I neaten things up on a non-mobile platform afterwards.

Requirements (descending order):

1) Extremely good text manipulation ability. I need to be able to select, cut, copy and paste text with ease. I've found manipulating text to be the biggest problem on Android-based apps.
2) Multiple (tabbed) documents open at the same time. I need to copy and paste text between multiple files at the same time.
3) Change font and background color. I like to make the background black so I don't get blinded / tanned.
4) Free would be nice, but I'll pay if it's worth it.
5) The ability to use Bold / Italics etc is nice but definitely not essential. Simplicity is more important.

I need to transfer files from / to the ipad, but I'm happy to use another app like dropbox for that. Again, simplicity is the priority. I want to write and edit pure text in multiple files at the same time. I don't need to share documents with other people or any of that stuff.
