"Install Ready application" is the point of the "Application Install Ready" page on the Maemo wiki:

http://maemo.org/maemowiki/ApplicationCatalog

Although the wiki won't (probably) scale to be a full-blown catalogue when there are hundreds or thousands of apps for the 770 (hopefully), at the moment the wiki gives a quick way of seeing which apps there are. Perhaps more importantly, keeping an eye on the RecentChanges page lets you know when new apps are being created:

http://maemo.org/maemowiki/RecentChanges

I'm concerned the ITT Software Page is too fragmented when there are only a handful of apps to install; and the perceived barrier to entry is probably higher than that of the wiki - meaning it could become stale, or even miss applications altogether :-(

Cheers,

Andrew
