I have been running Volumio on my old pi 3 and really enjoy it. I mainly use it as an offline Hifi streamer out at my trailer where internet and cell phone access is limited. I just let it run its own hotspot, connect and throw on a playlist. xender
I have been looking at upgrading my pi mainly to tinker with a new setup and also get a little fast speed when using the WEBUI. I was planning on getting the 2 gig version but have been considering the 4 gig for future proofing. Just wondering what the thoughts were which model to go with.
