Smartphone, lost one iPhone 5c 32gb in blue, to this day it's still on my icloud holding on to a little hope that it will one day come online, still love it.
iPhone 6, 2 years ago fought for it when 2 guys approached to rob me, shattered screen and on.
Normal phone, a few stolen, but the one that hit hard me was my Nokia 1100
I had my Samsung U910 stolen by a darn bustard in 2008, other than that I've had my MacBook Pro and iPad also stolen in 2013 (remote jamming)
Now I ensure to check the car is locked before I walk away.
Never had another phone/device stolen, touch wood. Everything is insured as well, in case I break it or it gets removed by nice gentlemen with guns and/or knives.
