I think the new system of wire transfer to your bank account is much much better than the previous system. By transferring the money directly to my bank account, I as a publisher save a lot of time and effort.
Earlier, delivery of cheques were dependant on Google's courier partners in India. Sometimes cheques were lost in transit thereby causing a lot of issues for bloggers/publishers.
Now, after setting up my account details, I get payment credited to my account every month around the same date. No more waiting for cheques, no more depositing it, no more waiting for it to get cleared. Isn't is a more convenient way?
There's nothing complicated about this system, there are plenty of resources available on this website that will help you setup your AdSense account with your bank account. Please use the search option and look for them.
