Differences between OsmAnd and OsmAnd+ What is the difference between the free version of OsmAnd and the Plus version?

The only info I found seems to be outdated. While using the free edition the only limitation I noticed was the hint that I can only download 10 different maps.
As of 28/03/2013 the difference is that with the free version is limited to a total of 10 downloads (maps, voice packages, etc) and does not support offline Wikipedia content.

I know because I tried the free version and then buyed the plus one to be able to download entire european countries. Also I think is a really good application for 7 euros.
