i have no regret buying any nexus device, include my galaxy nexus, price is cheaper and better performance than ipad, i dont play games often so those few seconds loading time and few FPS difference is not a major concern for me

not much advise we can give, people who like original android, having active community, first hand update of latest rom and use their device for development work then nexus is definitely the device for them

if you just want to buy a device with state of the art specs & features and fine with no rom updates after first half year then you might have to look at other brand, or perhaps Apple?

if anyone were to ask me what smartphone to choose i will definitely recommend nexus 5, for tablet i would say nexus 7, if they want bigger screen then go for samsung note or ipad instead
