Which software do you run on your R1?
For the moment
* -ipsec site to site and client vpn(libreswan)
* -pbx(asterisk) with usb gsm dongle(chan_dongle)
* -some "smart home" self made gpio software
* -video recording from IP cameras (yet only implementing, even in my most budget solution already ordered several external usb SATA bays with external power for ~15 bucks per slot, even had no thoughts of using internal sata - 2.5 inch TB+ are more expansive then 3.5 and latest need 12v anyway, one hdd is definitely not enough for most reliable persistence task and you will definitely not use fast 2.5 ssd on on-board port at least maybe some big data lab...).
community fixed ALL issues with R1 back then, Sinovoip did nothing to help.
I thought that why we have the community and hardware manufactures (both low (Allwinner/MTK) and high (Sinovoip) levels). Actually I had no major unresolved issues with the configuration above (at least those I know about) and I think it is more then enough for hw costs. We may also blame the distributor for not contributing. Reverse engineering and closed schematic is crap, yet we see the fact - r1 exists and works...
Just IMHO, maybe I am wrong, you seems like an experienced guy in sbc just don't understand such hate for Sinovoip
