I have started a page in the wiki to compare the mobi features of the various readers. It will take me a long time to figure everything out so I thought I would ask for some help.
Mobi Comparison is the name of the page. I have three tables. The entries are fairly obvious but ask here if you don't understand. Another section may be appropriate for conversion tools but I haven't decided yet. There may be more differences than I have identified. If so please add lines. So far I have grouped all PDA's in the same column but it may be that that will need to change as well.
It is only a skeleton but hopefully when it gets filled in it will be useful for people needing to support MOBI.
