When it comes down to it, I will probably just pay for palringo again, but unless i'm missing something, I believe that it would have been better to have 1 program with all the features (rather than a premium and a light) and then limit features for accounts that haven't paid the upgrade fee.
There are two reasons for me thinking this.
Firstly, I have already paid for Premium on the iPhone, paying for premium on the PC seems to be double handling for services that are generally free.
Secondly, If you are going to charge for the program and not charge to activate an account how are you going to prevent software being distributed outside of palringo.com?
