Well I understand SDK as Software Devel Kit... I have the N810 setup with scratchbox loaded at home. But why would there be apps in the SDK that you can install in your emulated environment that aren't out in one of the Maemo repo's?

What if I wrote a program that wrapped less with some other commands into a gui?? In the SDK evidently this would be fine as the package is there... but would never run on an "actual" N900 since there is no repository holding it. Or at least, that function would be missing.

This kind of disconnect I can see being a drawback in getting developers over to the Maemo platform.. if it's in the SDK, I would think it should at *least* be in the extras-devel..
