It's working pretty well. I certainly use my phone for some things, especially if I'm away from the house. But I've just set habits that if I'm doing certain things (writing more than a sentence or two, buying things online, etc.) I just default to a laptop.
Having a microwave doesn't force me to eat TV dinners for every meal. But sometimes it's convenient to just microwave food. Just not all the time.
I don't think avoiding phone usage completely is needed, just a shift in mentality towards favoring "I'll sit down and work on this when I get home" over pulling out your phone to take care of things when you first think of them.
Downloading music off the internet is just the next logical step after taping songs off the radio. Cassette tapes didn't really affect the music industry, so I wouldn't worry about this whole Napster thing.
So, when you're looking to not pay for something to head to a BitBucket, but if someone else is footing the bill (like a company with a real budget for more than $7/month) you'd prefer GitHub? Sounds like a win-win for GitHub.
