I have a nexus 4 that is battered, the back glass got broken a couple of years after I got it and I just taped up the back with black electrical tape.

My gf says I'm the worst geek she's ever known since I use a nearly 7 year old PC, 4 year old laptop and a 4 year old trashed phone.

So if my phone is an expression of anything it's that I don't replace things that still work.
