I'm more thinking along "Apps I don't want to see on the N900" among them... anything that would go to the cloud, sync with the cloud or send any data to the cloud for storage.

In other words I want software to obey me not the cloud or web2.0 and I prefer my data not clouded

I do hope it will be possible to rip out any such software and replace it with local alternatives. If I want syncing I'll setup my own syncml server and sync that
