Hello: I was partially following a sort of argumentative conversation in terms of the cost for upgrading from the freely distributed standard talks license to the premium edition. To fairly state , that's my precise main reason of significantly declining the concept of freely distributed software. Here in Egypt , there is a major network provider which offered a freely distributed screen reader to it's genuinely registered customers, and I' am among them by the way, it's popularity is similarly recognized as Vodafone in Europe , and at that time I was going to get my talks premium from talk nav , I proceeded onto that. To concisely allege my opinion , the correct attitude is to sell a device which perfectly compatible out of the box. That's just my very humble vision onto the subject. Mostafa Al'mahdy. Best Wishs. It's always hope that gives meaning to life. _______________
