I have not upgraded from PBP2.6C to PBP3. I am not going to upgrade now. If PBP3 added more commands to run the RTCC, SPI, CAN modules then I would leap. So can I up grade, say a year or more from now for the same cost? The bug fixes and new devices are good for 1 year. So then, it's another $50.00 for another year? If so, I can see the company loosing base with many hobbyist. I knew this would happen.
