I do not want to go deep into the details, but simply express my subjective opinion on this device. For detailed information hundreds of reviews are available on the web.
Display: 5/5
The Nexus 5 comes with an excellent display. Everything is razor sharp. Contrast, brightness and sharpness are for this price more than okay.
Operation: 4/5
For people with large hands or normal operation is certainly not a problem. For small hands, I see the problem. I do not think that everyone will be able to use the Nexus 5 with one hand (on Android 4.4 and its menu I do not go here)
Speaker: 3/5
The external speakers do what they should. But no more than that. Compared to the "flagships" of Nokia, Apple, HTC and Samsung already scratched the quality almost of a Witz.
Playing music through headphones is dependent on the quality of the headphones, ok.
Camera: 3/5
I was spoiled by the camera of the Nokia Lumia 920. The comparison would the duel between David and Goliath equal. Nevertheless, the camera makes the Nexus 5 beautifully crisp pictures when the lighting conditions are in order. Dark lighting bring the camera quickly reach their performance limit. Pictures appear blurry.
Appearance: 5/5
A matter of taste. My taste has been fully met. I love this flat, timeless design.
Delivery: 3/5
A Joke. No headphones. A pitiful instructions. That was it. Can you compare it to the delivering laced shoes without laces.
Shelf life:
At this point I'm going a little emotional. I would ask in advance before your pardon. The thing slipping when getting out of my truck out of his pocket and suffers a display damage, despite protective sheath. No. I am not a crane operator and go privately and not trucks. The fall height was less than 30cm. Hello There? The Nokia comes to mind when climbing a ladder (2 meters) from his jacket pocket and has a dent in the housing. Same underground. Then nothing. Unbelievable. As can form his opinion of himself so each. Therefore, I leave the point in assessing outside.
Conclusion:
If you want to have a modern, chic, powerful smartphone at a reasonable price that can access safely. For people with a certain clumsiness like me, I advise against buying. The part can withstand anything.
