I think your first point is brilliant, but your second I disagree with. $5/month is $60 a year, practically an impulse purchase for a lot of people. $10/month

I think your first point is brilliant, but your second I disagree with. $5/month is $60 a year, practically an impulse purchase for a lot of people. $10/month is $120/year. That psychologically adds an extra digit to both the monthly and years and that is also high enough to be outside impulse buy range. Anecdotally, I love dropbox, but I don't even fully use the 2GB free account (mostly text files). I would pay $60/year immediately for even a 5GB or 10GB plan on the possibility I might need it swiftly or to give me the freedom of tossing on some more pictures of the kids. But I can't justify $120/year when I still have space left ont he free account.
