Are You Going to Forego Windows or Mac?

I'm kind of curious about which platform has been the most painful to work with. I'm guessing it's probably Windows or Mac, probably Mac for somewhere reason. So as far as next steps, like we are not quite there yet, but we would like to extract out the other part so that everyone could use it. This is something that may or may not happen, but frankly, it would be very nice if we could have like book on something like an iPad. Can imagine.
