I've read the forums, Googled, looked at the BFL site - but still am not sure...
Has anyone on these forums actually seen a BFL 50 GHz system in action?
Sounds like BFL's design/production issues will result in my order for the BFL 50 GHz to be a larger, and possibly a couple of systems mixed to actually produce 50 GHz of capacity.
I did find this video/post which looks like the latest info
