yes, you are right. Your case is obviously different to mine. For me, the BPi-R1 is a nice toy and I really like to play with it
Im using a 2,5 SSD so there is no need for the 12V Output. At the next step I will just need the 5V output to power the BPi-R1 on the LiPo battery port. The 12V output is just now a option for me. Because I don' know what next comes to my mind to implement.
And you are right too with the productive use of the BPi-R1. A small managed GBit router and a hacked Fritz!Box and a Banana Pi would do the things too. But as I said, the BPi-R1 is like a toy, a hobby for me.
