The Nexus 4 is truly the first time I've felt a phone match the premium feel of the iPhone. It really is that level every time you pick it up.
I certainly agree, ATM I have two phones, a SGS3 and the N4 and am having trouble deciding which one to ditch, I like the simplicity of Vanilla Android but also like Touchwiz, each has its merits, I for one, don't mind the build quality of the S3, it doesn't flex when it is all fitted together, but IMHO the N4 is up a notch on feel and pride of ownership (If that makes any sense) I think I will keep them both for another couple of weeks just to be sure that I sell the one I enjoy the least.
