Word docs on iPhone

Hi folks,
I'm hoping you can recommend an iPhone app that preferably will read/edit MS Word docs? I go to meetings and would like to read our agendas and write notes on what is discussed. Also asking for my friend who takes minutes and eventually wants to do it on an iPad with an external keyboard.
there seem to be plenty of text editors out there but I don't want to have to to transtmer files from one app to another..
Any info/advice gratefully received.
