Their places data, reviews, photos, navigation, and street view are all adding a massive amount of value. They have shifted the goal posts.
Edit: I submitted two reports of bad StreetMap pictures a couple of months ago on the issue of the pictures being taken at night. In both cases the bot which handles those reports rejected my categorising them as "of poor quality", and I heard no more about it. But prompted by writing this post, I've just been back to the two locations I reported (on opposite sides of central London, one in Hackney, one in Mayfair), and now find that the StreetMap data is once more pictures taken in daylight. So thanks Google - thanks for telling me I was full of shit, but actually fixing the problem.
None of which has any real value to me.
This is where OSM should move.
For navigation, on the other hand, it's already streets ahead (pun unintentional) of Google et al... for those of us who travel on foot or bike, that is!
