I thought it might be a good idea for people to give reasons as to why they prefer SD or Internal NAND installation.
I have personally kept to SD for the time being on my S905 box.
I'm currently travelling and in a hotel and have brought the box with me. To get online with hotel wifi I needed to login using a web page. Thankfully having Android available to boot to, it meant I could open the browser, login so the device/MAC was recognised, then boot back in to Libreelec off SD will full connectivity.
This will be the reason I'll currently be sticking with SD.
(another option would be a small cheap access point/WiFi bridge (even better if it runs OpenWRT) to connect the LE box to, login using phone/laptop and then the LE box will also be online)
