Manufacturers of phones using Microsoft's OS would be hurt in the sense that their phones could fall behind their own Android models in terms of features. For example, multitasking support is something that most smartphone buyers want, and is available on most platforms.
Nokia could be hurt the most as the Finnish based firm was planning on launching a new line of Windows Phone 7 devices. With "Mango" delayed until 2012, Nokia could end up having to rely on its Symbian lineup during the holiday shopping season, when the company was hoping to electrify the smartphone market with its new Windows Phone 7 models. The manufacturer could release handsets with Microsoft's OS after the minor "NoDo" upgrade has been released, but Nokia was apparently basing its new WP7 line around the more substantial "Mango" upgrade.
