Good list of "firsts", even though you forgot some: first to implement x86-64/AMD64 which Intel copied 2-3 years later, first to implement inter-processor links (HyperTransport), first to ship 12+-core processors (Opteron 6100 series). As an underdog, a company has no choice but to be the first to implement many features in order to even remotely hope to stay alive. Even then, it's often not sufficient because there may be a lot of inertia, so a small technical advantage may not be enough to convince customers from switching from the market leader to the underdog.
