I'm building a product now and I'm struggling with choosing the Photon or the Electron but ideally would like to have both communication options without needing to choose one or the other WiFi or Cellular.
I love that the Electron and E0 have more pins compared to the Photon and I need those extra pins for this product line.
So having cellular + wifi on one board with all the extra pins the electron provides would allow me to integrate one processor with both Wifi and Cellular options. Cellular can only be activated if the client needs that feature but at least it's there if needed or wanted.
Bluetooth on the same board would also be nice if you guys can streamline the process of getting data from a web-connected phone or tablet that the Bluetooth connects to so that it can use the phone or tablet net connection to send data to the particle cloud. But that would just be icing on the cake and is not really in line with your core Wifi and Cellular competency that you guys have been working on for years now.
