Seriously, it's turning into the app situation. How many phones do you actually need? You're only gonna buy one, so how is 3 (or, as you actually pointed out, the number is 4) not enough?
Verizon has a good selection of WP's available. The only thing they are missing are the niche devices, such as the 1520/1320 (phablet) and 1020 (THE cameraphone). Other than that, what more could you want?
There was a time that AT&T was the place to be for WP's, unquestionably. But that's the past. Verizon has finally caught up.
It really comes down to how many of these circuses you've been through with Verizon.
When wp7 first came out, we wanted Samsung & Nokia WP7's. Where were they? AT&T.
When WP8 came out, we wanted the Nokia Lumia 920. Where was it? AT&T.
When the greatest smart phone camera ever, the Nokia Lumia 1020 came out, we of course wanted it. Where was it? AT&T.
When the first (and only) WP8 phone/tablet, Nokia Lumia 1520 came out, we wanted it. Where was it? AT&T.
Am I glad that we got the first shot at the Icon/930? YES! But those memories are still fresh. And this update situation has refreshed the sour taste that has been left in our mouths time and time again.
Edit: And it doesn't help that some of us, myself included, would still rather have the Nokia Lumia 1520.3.
