Ehm, Humble:
"The 190 at least solved a significant number of the ergonomic and engineering issues that doomed the 109 from the start"
What are you referring to? The pilot ergonomy in the cockpit I presume. Ok, the 190 probably had the best cockpit ergonomy of any WW2 fighter but that doesn't mean the 109 was that bad. And when facing the maintenance and manufacture aspect, the 109 was actually very good!
