I think if you're a pro, the $600 is not a huge deal, but it's far from free. $0.30/hr assumes that you're using their products 2000 hours a year, or 40 hours

I think if you're a pro, the $600 is not a huge deal, but it's far from free. $0.30/hr assumes that you're using their products 2000 hours a year, or 40 hours per week. I'd expect that someone like a photographer might use it 1-2 hours per work day, which ends up being $2-3 per hour. For someone like me that has occasion to use something like Photoshop or Illustrator 3-6 hours per year, the $100-$200 per hour is quite pricey.
