I wish - I've had attachments that I've tried to open in Google Docs that appear mangled on my iPhone (which is not fun when you don't have a PC anywhere nearby).

It's unfortunate that the case where you wouldn't really need to attach a Word document and should just paste in the contents into email (just some plain text) is the case where Google Docs works just fine, and the case where you really need a Word document (complex table layout & floating pictures) is the case where Google Docs just doesn't work that well.

I didn't say it's perfect. Neither .doc or .docx are read perfectly by any software, Word included.
