I call shenanigans.
> Email is the same everywhere,
...as with all mobile OSes.
> all the apps just works,
In contrast with iOS? I'm not buying it. "Apps just work" is Apple's selling point for their iDevices and that reputation wasn't just bought by their marketing department.
> plays any mp3 without complaining (my sodding iPhone never did!),
Pix or it didn't happen. What MP3s was your iPhone - with it's iPod internals - unable to play?
> Nokia Drive just works,
iCloud, Dropbox, and SkyDrive are available on iOS. Nokia Drive is better than all of those?
> maps actually work (again something my iPhone shot down),
iOS has Apple and Google native maps apps. What specifically is better about Windows maps than either of those?
> talks to exchange without problems,
...just like iOS, which licenses ActiveSync from Microsoft.
> is exactly the same as my old Windows Phone 7.8 device (no who moved my cheese),
Can't argue that.
> opens all my documents nicely, reads any pdf fine.
...just like iOS. I'll be honest: I'm having a hard time buying most of those examples as they run contrary to my own (and anecdotally, most others') experiences.
