Agreed, the problem I face is that the pricing is hard to make fair. As a casual user I might use a particular tool very infrequently but some users are using it commercially and getting massive value out of it. It's hard to get the pricing right so both users are paying a fair amount for the value they get. This is the same problem as "buy once" software though, $2,000 is too much for the home user while it's pennies to the corporate user.
