I actually JUST got my first 1520 two days ago. Used from some guy on CL. I know, I know...risky buying a phone off of CL but even riskier if it's a years old phone. Luckily for me it's working out like a champ and the latest Preview Release is working flawless (after subsequent hard reset.) I traded him a practically brand new Moto X Pure Edition. I think I honestly got a bit of a raw deal but this phone is in immaculate condition and I'd been eyeing it for a LONG time after sitting on a Lumia 640 and L1020 for a year and a half.
My very first Windows Phone was the Samsung Focus Flash and it's been my favorite OS ever since. Just something so inherently elegant about it. My adoration for it only strengthened when I grew up and bought an Xbox, leaving my PS roots in the past. That being said, I still believe the Lumia 1520 is STILL one of the best Windows Phone money can buy, probably THE best WP Nokia ever created, blow for blow. And it will likely always hold the crown for the last truly great Lumia device, by which all other Lumias are measured.
