Rich, no way; sued, sure
Theres a lot more to it than what you want; ie: would most people prefer to pay $15, or $30-$40 for the same thing, with a package and SD card? Perhaps more important is the $10,000 the dev would have to put down to get the SDs printed up before a single sale has been made, versus the $0 cost to get the DRM download right up.
You also assume DRM is evil; while I'm 100% anti-DRM most of the time, there are ways to make it work.. ie: I always said that if I made a DRM'd product, I'd try and make it so if the company gave up the goat on the platform, that the key-gen would become open source, or the unsigned binary woudl be released, or some other thing; it makes no sense to screw the buyer (which is usually people like me as you know
Anyway, remember, its my time and cash layout, not some faceless rich entity; I wouldn't make a SD boxed version.. I can't afford it, so thats 100% out at least for the first thousand sales.
The responses are more or less what I expected, so no worries; more positrive than negative, but naturally .. once a product is available, many fewer will jump in with cash in hand .. unless it really is good, and liked, and few other diversions to compete with..
I'll only do it if theres minimal cost, since its really mostly risk I think.
