grow or die this seems to me to be a statement, not an argument. you also imply that hobbists can't write drivers. does being a hobbist set some bit in one's brain that inhibits the device-driver region?
i suspect the real reason more devices are not supported is: hardware makers often make it hard or impossible to obtain specifications. there are big exceptions to this. ahci was fully documented, for example. with proper documentation there is nothing magic about a device driver that makes it any more difficult to write than anything else. by the way, there are plenty of professionals working on plan 9. (and at least 4 new drivers this year.) - erik
