haha actually I think the recording model(if its the one he is holding) is quite ugly, not because its flat, but the pickups, the pickguard...aiya everything la. But to each own's preference la. Flat top, arched top, all nice la if the wood has nice grain etc etc.
Like all shapes of bodies, excluding hollow bodied ones, I guess cannot say zilch to tone la, most probably less significant as compared to like pickup differences and wood type etc. Honestly, I can't really tell the difference, but I'm sure some people have more sensitive ears to pick up such things la. Moreover with the use of effects, EQ on the amp etc, tone is often what you make it out to be.
But I do agree though, if it was made flat top and much cheaper, it will be good for everyone. But oh well, a business is a business. 8)
