10 million, but how many owners...?
In my house, we have:-
1 Raspberry Pi 2 Model B - running OSMC and TVHeadend to act as a PVR recording to a network disk.
3 Raspberry pi Model Bs,
- One running OSMC as a media player and playing *from* the network disk.
- One is a print server
- One is in the process of being built into a low power laser cutter
and 4 pi zeros - used for tinkering, one of which is partially fried (SPI is dead, due to an accident with a NiMH battery, a loose jumper wire and a metal keyboard tray.)
We've also had a failed Model B, which has been sent off to whatever the council does with electronic waste.
So, that's those that have been bought for our household alone, and I'd bet I don't have the largest collection there is.
