I hear what you are saying, and I understand MS' line about it being a marathon, not a sprint, but with the public perception of Windows Phones combined with the fact that not only is the OS having to play catchup to get what is now basic features, it also has to play catchup to get what are considered advanced, 'wow' factor features that appeal to consumers. They really needed to get a big jump out of the gate and, as much as I am enjoying WP7 and support it, that big jump did not happen.
When the Iphone first came out it did lack features, but the entire platform was such a cut above anything else that it stood out. This was not going to happen with WP7, but MS cannot afford to keep taking this seemingly casual approach to getting attention to the platform.
Hopefully, they will pick up speed and momentum. It would also help if the hardware partners put out truly impressive and killer phones. I love my Focus, but my prior phone for 2.5 years was a Motorola Q9H so of course I am dazzled...but I wish it wasn't so 'plasticky' and it came with 16gb instead of 8. This first wave of phones for WP7 could have been much better.
