I could;and when they ask "show us all the apps you made with it on Google Play and iTunes" what will you answer then?
that the multi million euro earning app is already 5+ years in constant development and soon to be released?
I could show them many projects I developed and/or few apps published;
I could answer that to teach mathematics it is not necessary to be a brace, or that to teach zoology it is not necessary to work in a zoo or be a mouse.
Would you like to ask Erel how many Android apps he has released just because he... knows B4A and can teach it?
