Well, I think that a Wiki is a good tool to list the drivers, articles, tools, single hardware review. Possible for listing on a table the devices is the place where I have doubts about using it.
About the searchs, well there is any workarround we can do about that. Possible connecting googlo search to the site or trying to find another search script for MediaWiki. But I think that with firefox Crtl+F and the wiki search the searchs can be fair enought.
Plus, I want to be a collaborative site. What is more easy than a wiki for this. Instead of having strict submition forms this can give more freedom on the information I want to post about a device.
