Not in those apps yet. Lacking voice annunciation of turns they're obviously not as good a navigation device as a dedicated GPS like a TomTom, but can to get there without referring to a paper map. If I strongly desired the turn by turn functionality, my solution *today* would be buying an 18 month old TomTom from Ebay and using it for the next 6-9 months until the N900 gets closer to dedicated levels of functionality. I'd then sell the old TomTom at a smallish loss, and then use either the included (free) and upgraded version of Ovi Maps, or spend a bit more to get commercial software. The N900 would stay around for all the non-TomTom functions.
