Well, I read the list of first class objects on the wiki [1] but I still
had problems understanding what it means for the user. For example, what
if a user wants to calculate something - 'calculations' seem to be
missing.

I wasn't able to find the documents you were talking about but the
people in the #dashboard channel were very helpful: I was told, objects
are represented by so called 'tiles' in the beagle search tool. I
think, this means those little rectangles in the screenshots, with a
header and a preview image, etc.

I guess, the similarity to 'files' is intentional. From this point of
view, a file manager makes no sense anymore. Nautilus would be more of a
'tile manager', showing you folders of persons, documents, and other
objects.

However, it doesn't make sense to 'manage' tiles when they are
associated accordingly - why should one move a 'person' into the
'documents' folder? From this point of view, the move to spacial
nautilus makes a lot more sense, as well as several other stuff I read
on the mail archives but that just appeared as strange.

This seems to be the part I was missing all the time; it's quite funny
how you can get used to certain kinds of representations.

Oh, if anybody wonders what this has to do with marketing: It's
obviously always better to understand what 'products' you're trying to
market, right? ;-)
