The industry exploded over that period, so the stock price isn't an accurate indicator of how Apple performed relatively. By 1990, Apple was clearly not competitive. Microsoft was winning, and what they had was DOS!

I feel Nokia's management is doing what they can. No other handset vendor-developed OSes have succeeded. Blackberry, Bada, Meego,... The roadmap would have been shared way back when they signed up for this. Windows Phone 8 is the real deal; WP7 was too little, too late.
The other points are fine but isn't that just ad hominem? His points seem valid.
