Guess what they're saying is its an exceptional job considering Microsoft had to account for all the variants and prepare and deliver updates themselves, compared to having OEM's update their devices individually, which can take months for each model in androids case. Especially considering Samsung made actual hardware changes to their Focus device, which is an entirely different situation to having to provide customised software updates based on region or country.
Cant really downplay they did a good job updating all device, only barring the at&t DVP at the moment, which is in testing. Compared to the previous nightmare of trying to pry WM updates from the grim hands of OEM's, its definitely a miracle.
