You are absolutely correct. It amazes me how large of a market x86 commands with the undisputed worst instruction set design. Even x86 processors know their limitations and merely translate the instructions into more RISC-like 'micro-ops' (as intel calls them) for quick and efficient execution. Lucky for us, this translation 'baggage' only occupies, what, 10% of total chip design now? Had several industry giants competed on perfecting a PowerPC-based design with the same amount of funding as x86 has received, we would be years ahead of where we are now.
