I've played the waiting game on a few next gen items from small manufacturers. Heck I was even one of the small companies once. Delays happen, orders and their changes can over whelm a work load. It's a common thing.  Back in the early 3D printer days the Replicator 1 had a six month delay and the unit ran like crap upon arrival. But with the community doing and sharing mods it's been a multiple ROI machine for me.

Any new edge tech has risk. The do diligents research for the Acorns and the BCU was simple enough I thought. I jumped in with non essential money fully expecting delays because there are way to many things happening for a smooth time line transition. I also have a good feeling the FPGA thing in general will mature nicely so I'm not expect killer returns straight out the gate.  I'd much rather have a late delivered product that works than a unit I need to return do to a manufacturing flaw that was later fixed.

I thing I am disappointing in is the banter within both this forum and the fpga related discord groups. Oh well, dealing with an entitlement based irrational public is why I retired. Thankfully some out there still step up and push forward with a challenging product. That kind of dedication and talent I admire and that's why I opened my wallet.
