Hi Marcus,
I am with B4A since 20.09.2011 (German Date) - in this two months I found some strange ways of B4A compared with the basic I know from Windows, but after this 2 months, my app is nearly finished and I did start from scratch with android programming. The same for Windows Mobile with a french compiler took me nearly a year to understand that compiler.
The cost of B4A is so less, that it is worth every cent ;-)
And it does what its for, create fast apps for android !
And don't forget the help in this forum here, if you want in german too ;-)
