You're absolutely right. Look at the P1 wireless promise, It's abandoned as far as I can tell, but was used as a selling argument by both dealers and P1 themselves for quite som time before it all faded...
I'd also love to see WiFi included in the body, it's a fairly small chip that draws little power, and it must surely be perfect to send embedded .jpg's from the RAW files to handheld devices like phones and iPod's with wifi support.
I'm not a wirless expert or an IT guy, but in regards to medium format I think the issue with wifi'ing a medium format preview file to any kind of device, whether it be computer, Ipaq, or iphone is not so much the wi-fi, other than you need a some kind of wireless base station, but it's the fact medium format previews are pretty rough and unprocessed looking.
This part I've never really understood is how much does it add to the hardware and development costs to add a second processor dedicted to making simutaneous processed jpegs?
If you shoot a medium format back non tethered and show the image to an art director, then shoot a Nikon or Canon in the same manner, the AD will swear the Nikon has to be the better of the three cameras, just because that lcd is so amazing.
Regardless, I can't really overstate how good it would be to have hand holdable devices with a quality lcd that could be tossed out on location and the AD, stylist, etc. could just look down and see the images.
Sometimes I think everytime we take three streps forward we go one step back.
Early on with digital capture, using a Fuji S2, we tethered through the video port an ntsc signal to a 9" sony monitor and though it wasn't 24" Eizo quality it was very good, allowed everyone to see easily, the tethering was tech proof and simple and you could even zoom into the image.
We even sent a wireless ntsc signal out to other monitors to see the effect and it worked, though the signal wasn't that reliable.
Still, how could that cheap little Fuji S-2 be so close and now we are still looking at tiny lcd's (even 3") or hardwired to a computer with a large monitor.
Now, not to go off topic, but what the hell happened to Fuji? I would have thought that by now they would have a line of professional cameras, digital backs and full frame 35mm cameras.
Who really knows as much about color as Fuji, though instead they keep coming out with new films.
It really makes no sense to me.
