I sold my tmobile 5 16gb for $375 and bought a 5S new in box from CL for $600 - everything checked out at the Tmobile store so I ended up only spending $225 to upgrade to a:
Newer phone with newer battery (my 5 was starting to die a little quick)
Better camera
Fingerprint sensor for convenience
Faster (and hopefully even more so after the apps are updated to 64bit
New color
So to me it was worth it. Now if I had to spend any more than that I might not have upgraded. The 5 is still an insanely nice and good phone.
How did you manage to get a NIB 5S off Craiglist for less than full price???
