Have had my Nexus 5 since early November, using it naked alongside a naked iPhone 5. The Nexus 5 is nice but it's definitely not as durable as the iPhone 5, the glass and back are both noticeably scratched within 1 month while the iPhone was pristine. Don't remember the Nexus 4 being this manja although I hated the Nexus 4 for other reasons.

But the price was cheap and performance is excellent. Battery life is surprisingly good too.
