The question is NEVER how many were shipped.
The question is how many were purchased? Remember the Kin One and the Kin Two? A bunch of them were shipped, then marked down, then given away, then dropped and the phones they couldn’t sell or give away were shipped back to MSFT.
Personally, I think MSFT is too late to the party. They are at LEAST a year behind the competition in shipping, and more than a year behind the competition in features.
I haven’t seen anyone with a WP7 phone yet.
I agree that MSFT was late, but even worse they came in late with a mediocre product, and one of the worst marketing campaigns I can recall.
“Windows Phone...the smartphone you won’t use that much (or drop in the urinal).”
If WP7 offers anything that IOS or Android phones don’t, Microsoft’s ad agency has done a great job of keeping it a secret.
