That single icon is almost hiding Extras better than a snake is hiding it's legs. There is absolutely NO mention of maemo.org or the Extras repository on Select (but plenty of Ovi and Store marquees). The closest you get is a tab saying 'from Maemo community'. Then, when/if you unsuspectingly click an application's download button, suddenly you get the elusive Extras repo enabled in the background.

Even Bears with quite a bit of brain will not know what just happened there. They click download calculator, and suddenly BAM, 50+ free apps appear out of the thin air in your application manager. Still too close to 'easter egg' status, especially compared to the Ovi's (underutilized) omnipresence.
