Like I said, I have no intentions of moving on yet. Lol.
But you got me curious. Right now, it looks like the V20 is going for less than $100 in most cases. I saw some as high as $150 for mint condition with packaging, or with extra accessories. What's interesting about the phone, though, is it's a niche device. For the right buyer (I.e. Someone like me), they would be willing to pay a premium for it. I'd be willing to pay about $250 for one in mint condition. You'd have to pay me $250 for an iPhone to take it, which I'd give away, buy a V20 for $150, and profit $100 on the deal. Lol.
To not derail too much from the thread, this shows an inherent flaw in making a purchase decision based on resell value. You can make some guesstimates on how likely a phone is to retain its value, but the market is always shifting and there's never a guarantee on that retained value.
