Hi, I am a member of 3 development teams, all of which will never use Xamarin.
The first one is my full time job at a medium sized development company. We have 5 developers, so to target iOS, Android, and WP8 it would cost us $15,000 per year. Management would never approve an expense like this. Even if native development would cost us more time, they would still rather maintain and learn native code bases then feel robbed of $15,000 / year.
The second is a side project with some friends. We are interested in targeting iOS and Android, but we need to use WCF. Too bad you need the Business edition to use WCF, so me and my group of 2 friends who have no income or funding are expected to pay $6,000 per year. Even if we saw value in this, it is not financially possible for us, so we will do native development also.
The third is my solo development. Again I am interested in what Xamarin is doing, but I also would want to use WCF. This leave me personally paying $2,000 per year to target iOS and Android, again unacceptable and I will be learning native development and never using Xamarin.
I don't know who came up with this pricing but it's ass backwards. Change your pricing to scale with size, not limit features, because even small teams and projects can use features like WCF and SQL.
I was excited to hear that Xamarin would keep Mono alive, now I'm just sad to see such a great open source project go to shit and attempt to gouge it's clients.
