It's 5 dollars. Stop being cheap. Buy it if it sounds like something you'd like, if not, don't buy it. You don't get a demo of a movie when you buy it. You can't just watch half of it and then decide if you want to buy a ticket. It's pretty obnoxious when tech-types bitch about $5 yet have no problem billing clients $100+ per hour or making $100K+ per year as a developer of the very types of things about which they complain about paying $5. It's not unlike restaurant waiters not leaving tips when they themselves go out to eat. Not everything needs a demo. Perhaps a quick screencast or something if you feel like the screenshots don't do the product justice. But it's a text editor.. how much demo is actually needed?
