The questions I would have liked answered did not get answered. Instead we got some silly quasi-religious themes, complete with angels. The show went out with a whimper instead of a bang. My take on the ending below.
[Spoiler alert]
Finding a habitable planet (a new Earth) with pre-technology natives, the people leave technology behind, fly all the technology into the sun, and help repopulate humanity by blending in with the locals (or not). We then flash-forward 150,000 years, and left with a prophetic warning (complete with a cameo by co-producer Ronald Moore) about the dangers of robots. Then exit with Jimi Hendrix doing “All Along the Watchtower.” 
Maybe more fully channeling the end of The Matrix by playing Rage Against the Machine would have been too much to ask. A little wink with someone keeping some advanced technology around would have been slighly more interesting.
