When I initially got the keyboard and it was having the stuttering issues, I gave the bluetooth option a try. It ended up giving me serious input delays, so I switched back to the bolt which was at least usable.
Since I had just gotten a newly released 7950X, I figured it might be a BIOS issue, but subsequent BIOS updates never solved it.
What went wrong was greed. They should have sold to Microsoft when it was offering them a ridiculous amount of money for a business that was already on the decline.
A few years later they sold themselves for about $5 Billion, which was only around 10%-11% of Microsofts final offer.
