+1 to Lightwizzard's posting. I have seen lots of complaints about the Solo4k in other E3 forums. Not sure if it is against board etiquette to refer to other distros forums, but this particular one has been very vocal about the driver issues and lack of support from VU+ to fix the issues. I don't know if it is VU+ or Broadcom at fault here, I have heard some comments that Broadcom can be very slow in releasing driver updates so perhaps VU+ are stuck waiting on Broadcom. Either way there appears to be more disgruntled Solo4k users than happy ones, at least on this other forum.
