Better remote control for more expensive models, than now, where ZIDOO gives the same remote control ($ 15) for the cheapest but also for the more expensive model. Other manufacturers (for a more expensive model) have at least two remote controls IR (with numeric keypad) and BT. I would welcome the LCD display to show the time even when the unit is OFF or in sleep mode. Support for stream services. The multimedia device for launching only LOCAL film is now "passé" When people wrote complaints about Wi-Fi antennas that can't be unscrewed, ZIDO will learn from it. Of course, the Z9X has a fixed Wifi antenna again. Overall, I don't understand the price difference. The same motherboard, the same LCD display for all models (pure marketing) , but the price of a few $ 100 just for a different look of the box. If I pay extra for the PRO model, I would like to see the difference.
