iWant: Maybe Not. (Yet.)
Well tonight’s the night:

You know what? Despite my earlier feelings, I’ve decided that there are far more important things I could do with $600 — $800+ if you include the change in cellular providers — than buy a phone, even if it is from Apple.
That said, I’m going to be watching how the proud new owners react, especially over time. David Pogue, for instance, said that “it mostly lives up to the hype,” but that there were some shortcomings. Apple’s good about second-generation products being better than the first, so I’m assuming that an iPhone Mk. II would address many of those issues (that can’t be fixed by software updates on iPhone, the original) and things that haven’t even been brought to light just yet.
Plus, I really could care less about the iPod portion of the phone. I don’t see Apple doing a non-music-playing version of the iPhone, but hopefully future generations would either a) be cheaper, meaning it could co-exist with my other electronics or b) have enough memory that, for instance, I can back up all my Compact Flash cards on a job. (A larger screen to show photos on would be nice, too, something probably appreciated by those who will also use it for video.)
Further, I haven’t yet been able to get a straight answer on NEF support (Nikon’s RAW file format). Anyone know?
No matter what, Apple’s made a splash with this device. When I drove by around 3pm, the line at the North Macon AT&T store was six or seven people deep — remarkable for a mostly-empty strip mall in economically-depressed Middle Georgia.
Heheh. “Y’all got a sweet Apple there.” Maybe soon.

Comments:
You want to know if iPhone supports NEF? Hm, that’s a good question. I don’t even know the answer to that, and I do customer support for the iphone.
Best bet: Don’t call ATT, call Apple. Apple will know. =)
Thanks, Ted.
OS X does icon previews, and includes native support for NEF in iPhoto and Aperture, but I don’t know anyone with the camera connector and a recent iPod with which to test it.
I wonder if the iPod camera connector will work with the iPhone, now that I think about it. Knowing Apple, a slightly different $29 device will be needed…;)
