Regarding #1, I have released more side-projects since I became a father. I'm still not a wonder of productivity, but I certainly did cut down on casual browsing, chatting and TV-shows.
I know that I have (if I'm lucky, doesn't happen every day) 1-2 hours to spend in front of my computer. That time is more precious and used more productively than before. When I'm really motivated I plan ahead, and might already know which bug to fix when I get some time at the computer.
I think this also tangents some other comments about "do something else". I never have time to sit at the computer when I get home from work - I might cook dinner, read a story, play in the garden, prepare for the morning... and after that I'm more likely to want to do some coding (or whatever) again.
