I think we should clear up some confusion on this. I think many people are caught up on the Price and also wrongly think SambaPOS is not a business. SambaPOS is a business and obviously Emre and his Partner want it to grow and they want to be able to sustain it with resources. He could easily charge $1000 a year for it or even $100 / month and that would give him resources to create Top Class support and hire many people to write the best documentation.
He has stated many times that SambaPOS will remain the best value and provide the best solution for your business. Profit is not his priority. If we as the community expect to have the same level of support and elaborate very pretty documentation then that takes resources which means it takes money.
Obviously he is taking everything into consideration so we ask everyone to please understand how this works and please be patient as we make steps to improve the community this includes improving documentation.
Bottom line is you must understand how limited resources are with a project like this. Emre is and will always consider your thoughts and the communities thoughts. He will weigh his resources and he will deliver what is the best for the community with his resources available.
Obviously community wants more from SambaPOS and more means it will cost more resources to make it possible this was partly why there is a small fee. The more demands and the more community wants or expects from SambaPOS the more resources it will take. Emre would keep it free if he could but right now the resources required to deliver what community needs can not be done for free. Additionally increased needs by community will put more pressure on him and his partners as they try to meet demand and balance resources.
Please be patient we as the community can help him help you by contributing to the project with Time, Ideas, Help, and even Donations.
