Confluence wiki
Pricy, but excellent enterprise wiki, complete with Word-like editing tools, which means that you do not need to fight with wiki-markup-language to use it.
You can install your own wiki, if you have access to a server, or you can buy access to a wiki, which is hosted on the Confluence server.

iPhone users: You can download a confluence app form AppStore and access your wiki from your phone.
