I'm hopeful this is just the first cut, and there will be subsequent releases adding the missing features at which point it could be installed by users as well as developers. If (big if) that happens, then users have the choice to cut over to OS 2007 or stick with OS 2006.

Either way though, while this remains a "hackers only" version it still means developers face the choice: continue supporting 2006, support 2007, or both. If Nokia put more weight behind OS 2007 on 770, developers wouldn't have to make that choice. Lets hope OS 2007 on 770 turns out to be better/easier than Nokia thought and maybe they'll change their mind (I'm not going to hold my breath).
