Same here, but the camera is horrid, and the speakers are sub par to most phones in it's class. Not to mention battery life is mediocre.
The Camera itself isn't Horrid. its google's software for the camera thats absolutely dreadful. You'd think they'd be able to see all the Skinned Androids and their camera software and realize what they have is junk. Seriously, go use a 3rd party camera App on the N5, and the camera feels normal again.
Speakers do indeed feel weak. but for fully unlocked retail price phone at $300 less than the competition, you do expect some minor sacrifices. The single speaker is quite loud, but man, is that sound, just not very crisp.
I've managed to get a day out of a battery charge now though. I changed my runtime to ART and I use ES Task manager to make sure widgets and apps i don't use frequently don't sit active using battery.
However, The N5 is pretty damn close to the $650 phones in actual quality of the components and device.
ONTOPIC:
I think Apple, while they shouldn't be afraid.. should be keeping tabs on the competition. Blackberry didnt, and assumed what they were doing internally was good enough... it backfired. All companies should be mindful of their competition in order to survive.
