"purported philosophy" ??
Personally speaking I am a lot more interested in some "purported philosophy" for their intended usage, since I plan to *use* the chuffing thing (or not as the case may be).
iPhone "purported philosophy": you are only allowed to do what we let you. And you must use iTunes.
Android "purported philosophy": you are only allowed to do what we let you. And we are going to aggressively mine your personal data.
Windows Phone "Purported philosophy": you are only allowed to do what we let you. And you must use Zune, Office and Skydrive. Buy more Windows. Buy now. Because nothing that you've already got will work with this (the 'you' in this case is particularly me, some fan of Windows is likely to have all of those things, but I'm not getting them), oh and based on our previous behaviour you can expect us to aggresively mine your personal data and sell it to the highest bidder.
You know, I would really like to be able to get hold of phone that was entirely agnostic about whatever other kit and services I use. One that just worked because it adhered to standards, and did not need to know what kind of other stuff I've got, or stalk me for personally identifying information.
I particularly do not want Zune desktop or iTunes in order to be able to get media on and off my phone.
So yes Windows Phone has a fancy shmancy UI, and the People Hub looks very useful. But. Unless I ditch my existing investments, or compromise their utility, it's not a whole lot of use to me.
And get guess what. My current phone implements some standards nicely. SyncML, Bluetooth, DLNA, USB-media, USB-on-the-go, HDMI, WebDAV, etc. Unfortunately the UI is a bit of a sow's ear, and somewhere it has developed a nasty memory leak which means I need to restart it a couple of times a week, so I should be looking for a next gen replacement...
Strangely Android actually appears to be the least evil option in terms the compromises I have to make in order use it (and given that Google is already aggressively mining my personal data anyway, there is no actual net increase in evil done to me).
