B4A is worth a lot more than what what is charged for it, and as others have said the support is excellent.
I have memory problems especially getting my mind around new ideas and despite only having previous experience with old school basic (from the speccy and Amiga days) it has helped me to write and publish my own android apps.
I love the fact that it puts the power of android in everyones hands, without the need to learn java programming which I for one tried but could not get into.
Although I do wonder if Erel has figured out the key to human cloning as not only does he find time to work on B4A he also somehow manages to be very helpful on the forums and I have no idea how he finds the time but am very glad he does
