The technology is on the move and they have to give it a name. To make it easy for people, a simple table would do. Nokia should be posting it because it's their baby. Nokia seems less tuned in than the experts on this and other forums. This website could host it in a wiki but there are similar sites out there and they will have to do it also if Nokia doesn't do it.

It would have been great if Nokia stated in their user guide that periodically the firmware gets updated because technological advances and that owner should check periodically to see if newer versions are available. They should also say what the upgrade is going to give you. I honestly don't know what successive versions of the 2007 versions give. Since I haven't upgraded to anything yet, I have no clue what to expect. Most of the new features are mentioned anecdotally in the various forums without a comprehensive description. Nokia seems very hands-off on this, depending on forums to do the work for them. The closest thing to a grand view comes from maemo.org and that's great. Does maemo.org belong to Nokia?
