Pfeiffer "User Experience Shootout"
Pfeiffer Consulting recently did a comparison between ios7, ios6, (Samsung) android, BB10, and WP8. The report got a number of facts wrong, or were blatantly biased
They complained about not being able to set a background image on the start screen. Why would you want to, you wouldn't be able to see it anyway?
They complained that one can't customize the tiles. Except iOS can't do that either, and they didn't mention that for them. Besides, it's all up to the developer to be able to customize the tiles.
They complained about "advertisements on the home screen", which was actually some easily deleted Nokia bloatware. They must have forgot to mention the bloatware from the Samsung phone.
They complained about not being able to change the search button defaults to Bing. If you really hate Bing, use the browser like on all the operating systems, maybe if they had search buttons with changeable engines, this would be a legitimate complaint.
They complained about there being no way to specifically eliminate an app to free up memory or resources. Except there is, just go to the app and press the back button until it closes. I'll admit it's not a great way, but it is there.
And the worst mistake of all... They complained about inefficient use of screen real estate saying "iOS displays 24 apps on its home screen, while Windows Phone 8 barely manages 12" This is completely false, using all small tiles, the Nokia Lumia 920 they tested on could show 28 tiles, more than iOS
