Shawn Blanc, on Android 

In his excellent, in-depth Nexus Galaxy review:

But my overall impression after using Android for a week was that of being underwhelmed. Though the operating system is functional and advanced in certain areas, it still has an overarching feel of still being immature. Moreover, there was nothing on Android that made me feel more empowered compared to using my iPhone.

Sure, there are bits of the Android OS that I like and appreciate, but never once was I wowed or delighted. Which is unfortunate, because those are important elements when you are using a device day in and day out every day of the year.
