I have autocorrect turned off on mine; It never guesses my words correctly for ANYTHING and I'd rather just upload it and edit SP problems there when I have the time and patience to do it.

I use the Documents2 App, which is really just a bunch of txt files categorized in folders xD The free version is pretty decent for something, well, free! I've heard of other Apps which are probably better, but I'm cheap and it works for me xD
