You're the Pundit: What would make the new iPhone a "must buy" for you?

When it comes to evaluating the next big thing, we turn to our secret weapon: the TUAW braintrust. We put the question to you and let you have your go at it. Today's topic is the new iPhone.

Last year, I was looking forward to delaying my iPhone 4S purchase (or the "iPhone 5" as we were guessing) until November, when I would have received a huge price break.

Then Siri came along, not to mention that amazing camera, and I was hooked. I bought my 4S the first day it was available. I spent hours attempting to place my order, and then went and wrote an entire book about Siri with Steve Sande.

Today, I was talking to the TUAW gang in our back channel, discussing what features would make us reach for the "buy immediately" button on our Macs rather than delay our purchase for a better price

For me, it's haptics, similar to the ones used on the Wii. If Apple were to introduce a haptic-enabled system, I'd be there like *snap* that. No one at TUAW expects this to happen soon, primarily due to the battery-consuming nature of the beast but a lot of us would love it. Imagine if Apple could push touch feedback into the user experience! Haptics solves a real problem -- the lack of physical response on the otherwise featureless glass interface between the user and the device

Other TUAW-ians are hoping for (but again not expecting) NFC, aka near field communications. This tech uses radio communications to communicate with objects within a few inches of each other. There's a lot of cool applications for this from shopping to contact-sharing to public art installations.

Speaking of near-object-communication, that Samsung phone tap-to-transfer trick would be really cool to have, especially if it's realized as "AirDrop for iOS". Right now, you can beam your photos from one iOS iPhoto install to another. Why not push that to the next level?

We figure it will never happen but light field photography is now out there in the market place. So why not bring it to the new iPhone? Just point-and-shoot and you can focus after the fact. That would be an amazing must-buy feature for many of us.

Or, how about stereoscopic photography? Much easier than light field to implement, what if Apple simply added another camera to back of the the phone to enable 3D image capture? Tie that in to some funky software and you'd have a feature that wouldn't cost to much to ship, but add a great fun touch to the new iPhone. We already know that some level of glasses-free 3D is already possible on iOS.

Which of these new features would kick you out of your contract-lethargy and into paying the early-upgrade penalty? You tell us. Place your vote in this poll and then join in the comments with all your analysis.
