Zoho Writer is becoming a worthy alternative to Word, Google Docs and Apple Pages, offering particularly good collabortation, navigation within a document and a well-designed, clear interface.

However, my experience is that Writer 1.6 has some stability issues. I frequently experience quits on opening a document. It appears more stable when actually writing. I have never experienced any data loss. But the 'quits' are annoying! Something to work on.
