Microsoft copies apple? I'd say the exact opposite, take a look at history...
I wasn't speaking software-wise, but rather newer philosophy-wise in doing things. Look, Microsoft had Windows Mobile, which if it continued developing would be where Android is today, Android was the new Windows Mobile, it continued where Microsoft left. They saw how well the iPhone was doing at that time, so they scrubbed everything they had and started from scratch. They chose a new model, a basic one actually, just because Apple did and was successful. They forgot their roots, and started doing what the others did.
I'll give you some examples so you'll know what I am talking about:
The iPhone was so basic that it had no ringtone selecting, no notification center, no smart dialer, no quick toggles, no file manager, no Office capabilities, no extensive camera app, not customization what so ever, no Media scrubbing, a basic media player.. The list can go on and on, Microsoft had so many of those already, but they scrubbed them, and many of those are retaining these days as when Apple does them, they do the same. The iPhone gets a notification center, hell we will start working on it now! It's now more customizable? Yes, this is where we should focus! It's not that simple anymore? Yes, neither are we (are going to be eventually). Believe me, if I sat with you I'll give you so many examples of the things that they could easily have, and did have, but scrubbed in the sake of what's happening with Apple design and software teams.
There was an article that day on Pocketnow by Adam Lein, he was talking about how basic is the newer Office apps, and comparing them to the versions that Windows Mobile had before 6 years, do you know that the Office app was far, far, far more functional than the one we currently have five years later?
FYI, I am one passionate Microsoft fan, I just state what is true to my eye.
