Why would you replace it?
Switch to a cheaper contract and wait a year or two for something worthwhile to come out.
Phones aren't purely about utility for me. They are also toys and who doesn't like new toys.
I'd love to replace my n5 with something new but I just can't find anything that I like 5.5" screens are a no go for me and I won't be carrying a huge bum phone in my pocket! And sadly, every maker thinks that 5'5"+ is the perfect size! Grrrr

Was looking at the Z3 Compact, but sadly still a step down in screen quality.
Contracts are usually irrelevant anyway, I've been on sim only for 2 years, but sometimes you can negotiate good deals.
