His LG was most likely the Quantum. I came from WM 6.5 the LG Expo. A phone way ahead of ts time with its attachable projector. But on opening day of WP I bought 2 Quantum's. Then I upgraded to the HTC Titan, then I bought 2 Titan 2's, then I bought 2 Lumia 920's on launch day, and I got the 1020 on launch day. So I guess my wife and I have been through 8 WP's in 3 years.
Lumia 800, got me hooked to WP.
Lumia 820 on launch day, buggy little thing which I sent in for repair thrice (my country doesn't do exchanges). Sold for a
HTC 8X. The display was gorgeous. The design and feel of it is fantabulous. But ultimately it's still not a Nokia and it's lacking software wise. Sold for a
Lumia 920. Happy with it so far! Might consider the 925 after I get bored of this 920
LG Quantum which I loved, and just recently did the upgrade to the Lumia 925, lovely phone. Also picked up a Lumia 520 Go Phone for travel and that's a nice inexpensive option with big storage for those times you don't want to risk ruin to your high end phone.
