I am guessing behind the scenes they probably had a target of 110Mhz. They probably hoped to hit that by launch, and sent out review units a bit early. However, whatever fix they were trying probably didn't pan out or they found another failure case in edge case testing (e.g. running it long term in places with high ambient temps), and had to throttle them down for everyone. So, the critical mistake was probably sending out units too early. Can totally understand how infuriating it must be because you buy based on the benchmarks, and don't get what you think you're buying.
