First, I want to applaud this achievement. 5$ for a little computer with a 40-pin with 26 GPIO is quite amazing in term of capacity. They are getting real closer to get a price tag low enough so it'll enter the manufacturing of some SMBs. I wouldn't be surprised if we start seeing those into some toys or drone real soon because it just cut the development time drastically.
But I'm saddened that it still doesn't come with WiFi. The ESP8266 is a good example on how cheap and small it could be. You could scrap the huge Ethernet port and still connect to the internet. Also, I'm frustrated that the Bluetooth didn't become the standard it should be and doesn't install easily on the Raspberry (or Windows for that matter) so most USB port could be remplaced by 2-3 USB-C port (You could use one for display and one for power).
In my mind, the ultimate RaspPi would have :
- Same specs as the RaspZero or better
- WiFi and Bluetooth integrated
- 2-3 USB-C port
- 1 Four-pole 3.5mm connector (Analogic Video + Audio)
- Micro-SD slot
- 40 pin with 26+ GPIO with a few more feature (Surge protection, Drive, more power, Possibility to raise to 5V, Analogic GPIO, etc.)
