High specced and premium are two different things - my Nexus5 is a great phone, but my 2 year old iPhone5 is still more usable, looks better and has more apps (that I actually use).
Nexus 5 is a great deal - I just would not consider it premium (even when I bought it last Nov).
I use a Nexus 5 as well. Best phone I've ever owned (and I've had an iPhone before). What exactly makes the iPhone "more usable"?
I have an iPad Mini Retina and Nexus 7 too. The iPad wasn't worth twice the price of the N7 but I had to buy it for development.
