^ what was the disaster with the GNex? Sales numbers? Timely updates?
Also, can I get details on how to keep the unlimited data? I can't just upgrade to another of their 2-year contract phones? If that's the case, I'm just going to keep my GNex as it still works perfectly fine. Not really a latest-and-greatest kind of guy, especially @ $500.
The Galaxy Nexus was just severely mishandled by Verizon. Verizon still demanded that Google preload some VZW apps (not that they couldn't be disabled/removed), they had to certify releases so they were delayed from regular Nexus releases and Verizon limited applications that could be installed from the Play Store (Google Wallet).
It just wasn't a real Nexus phone on Verizon. And I don't think Google is interested in building a Verizon-specific Nexus device again any time soon.
If you have unlimited data on Verizon, if you use a subsidized upgrade you will be forced to choose a new plan. Look at your usage. If you don't use more than 2-4GB of data, it could be the same price per month or maybe a little bit cheaper to move to a share everything plan, depending on your minute usage. You can get unlimited text/voice and 2gb of data for $100 a month. Even if you were on the most basic voice and texting plan with unlimited data that gave you 450 minutes you would still be at $90.
Every situation is different and everyone's usage varies. Make the best decision for you. I will say that if you are on the cheapest plan they used to offer and you decide to keep it and buy a new phone outright, like a SGS4, you'd pay $650. But, if you switched to the share anything plan and bought a SGS4 subsidized, the net cost would still be pretty high. $200 for the phone and $240 in the extra $10/mo in service. That's not much difference to keep the unlimited data.
But yeah, for used phones your choices are pretty limited. A SGS3, DNA, iPhone 4S and RAZR HD would keep you around the $300 range. A Lumia 928 would bump you in to $350-ish range. A Note 2 would put you at about $400.
If you have a GNex, nothing that really runs below $300 is worth upgrading to. Unless you want to switch to Windows Phone. You can get a Lumia 822 for under $200 and a HTC 8X for under $250, usually.
