The thing that most impresses me about JetBrains' products, after the very real "This was made by developers" feel to them, and the excellent community interaction, and the regular and plentiful updates.. is the price. They don't price gouge their users. They could double their prices and still have plenty of sales (but I guess they'd probably lose a lot of personal licenses.)
I'm sure they have actually done the numbers and perhaps even determined they are making more money this way, but from an outside/ignorant perspective it sure feels nice for a company to not have some MBA pushing that profit curve for all its worth and delivering damn good value for money for once.
