I'm a little curious (slight thread hijack):

Every time I see someone mention extras-devel it comes with the "kills kittens" warning (which is fine)... and like jaem said the problem isn't necessarily the app the user wants from extras-devel, but accidentally updating the entire device from extras-devel. If someone see's a post on here about XYZ app that a bunch of people are using it without problems.. for the most part (barring oddly unique things with their device) they are fine to also install that app from devel.

I assume, since Maemo 5 uses apt and is debian based, that it supports Pinning? Why hasn't anyone written a how-to for enabling testing and devel.. and then using pinning so that the maemo and extras repos take higher priority than testing and devel? This should, I think, prevent the device from trying to update/upgrade everything - and for packages that are in 2 or 3 of extras, extras-testing, and extras-devel, requires the user to install by hand, with a special command. Or does the built-in App Manager not support pinning and recommend you update anyway?

I'm just curious.
