Looks promising, but I'm hard-pressed to think the $40/individual price point is reasonable. $10-20?
You buy Xyz 2002, you get to keep Xyz 2002 and get some updates. When new and shiny Xyz 2004 comes out, you look at the spec and decide if new features worth the upgrade cost.
Same here, except improvements are gradual and not packaged into yearly releases.
At least the beta is still free now. $50 which is the default price, is too much.
Good software costs money.
