What I find quite amusing about this whole dialog is the amount of billable time that was sacrificed in order to rant about $33. When we first purchased ICG's Builder's Cad software in 1991, it was somewhere in the neighbourhood of $10,000, mind you, you did have this cool isometric view that was...wait for it...'shaded'.
If $33 is too much to pay for a full version upgrade, with free incremental version updates, then you're expecting a bit too much from the developer...unless of course, as a registered architect, you're only charging $1.81/hr. for your valuable time.
Just because there are incredibly generous contributors out there, like TIG, THOM THOM, FREDO, etc., a precedent is not established that says everything needs to be free, or it's a rip-off. According to what I've read prior, the version 1 software was used for 2 months...is it remotely tactful complaining about a usage fee of 55 cents/day?
Maybe the global economy is worse than I thought...
