How exactly your description of Sony agrees with my recent experience of Sony !
Recently I bought a Sony laptop and found that it has windows vista. When I complained to them that I prefer windows xp (since most application software for vista are still unavailable) they said they can not downgrade their operating system. The impression I got after talking with them is that they seem to think they are a great company and we can buy their products if we liked but they do not care.
The three points you mention certainly does not apply to Sony. You have said
Blinded by success, then blind to innovation
May I add
Blinded by success, then blind to innovation and people
