The more emails a company gets saying:
a) I bought X because of your BeOS driver
-or-
b) I did NOT buy Y because you don't support BeOS
-or-
c) I have Z and I want a BeOS driver or I will never buy from you again
the more they will listen. From what I here, Be will write the drivers, but Nvidia hasn't given them any specs. They're bastards, that company, with that review scandal and all...
