I've been using Quickoffice for about two months and almost entirely for word processing. I often have problems with autosave failing after the second or third successful attempt. Other than that, it works pretty well.
Keep in mind that you will have formatting issues when passing a doc between the iPad and a PC. This can be a real problem if you need to use a template. The lack of a word-count tool also is a major drawback for the type of work I do. The font selection also is limited.
