I just sold mine for a HTC One, i got 325 for a mint sim free one, at first I was thinking had i made the right choice, the One is so small in comparison but after a few days of having it i'm glad i made the decision to change
There are rumours of a HTC One with an 'over 5" screen' being in the works. I'm waiting for this before I decide on my next phone.
I nearly bought an LG Optimus G Pro to replace it but with the rumoured HTC & the Note 3 not being announced yet I thought I'd do best to wait....
