It's been discussed ad nauseum, but this is always going to be the case. If you hold out for the Prime, the minute you get it home you're going to see a leak for the Droid HD (RAZR) or whatever. It comes down to what you need vs what you want vs how long you're willing to wait.
There's def some things that leave me yearning for better. For instance, the idea of a better screen (especially after how much video and live streaming I've been using) is especially enticing. But I also know that a better screen isn't going to be as good in sunlight, and is going to impact battery life, two things I've also come to greatly value (especially with battery life, this thing is great).
Then take into account where you purchase your phone from. With the Costco bundle, even if I was capable of waiting for the next phone, that deal was going to be hard to pass up. It will not be offered with the Prime, if it comes to Costco at all (come on, you know we got the best deals
).
