AndrewDuffell: "I have to wonder how OreganoUK is a viable company."
Setting up a limited company isn't terribly expensive. Richard Brown doesn't only do RISC OS related work.
As for sales, there are still plenty of people still using Oregano 1, or older browsers like Fresco. So these are potential upgrade customers. In addition to that, there are all the copies supplied with Iyonix systems.
