Personal view; I don't mind paying e30 to ensure my hobby is supported.
Hopefully more people will feel this way.
It seems strange to pay for things twice, and is probably what is concerning some users.
I don't see it as paying for things twice, especially at the low price that OS 4.1 FE will be sold for. I guess that you could call it paying to get access to those features sooner.
Don't worry, OS 4.2 will be worth its price based on the new features that it will bring (i.e., features that won't be part of OS 4.1 FE)
