Windows Phone Thoughts: Help Files on the Pocket PC

Marcelo Bona Boff, a Pocket PC Thoughts reader who's working on a project for school involving Pocket PCs, asked me to post the question below. It brings up an interesting point - are help files on the Pocket PC very helpful? I have to admit that I never look at them, largely because they're usually so useless. A flat data file can only be so useful. Marcelo aims to possibly change that by creating a help file format that supports a table of contents, index, and search functions. The question below is aimed at developers, since they're the ones who would chose to use this in their applications.
