I couldn't agree more, I'm not a wealthy person and while $70 might be chump change to some users, to me that would represent a large amount of money - I couldn't justify to myself to spend it, I would love to be able to pay like $25 or $30 because I would probably be okay with that.
I just don't see the differences between the two being enough to justify me spending that amount of money, especially not when I'm doing just fine with Sublime Text 2 (and yes, yes, the old Hammer being used as a screwdriver argument will inevitably pop up now I've said that) and have no real reason to switch.
