.....there is just no way that a screen that fits on a DMFB can show the subtelties the back can produce...heck my MBP screen can't show them....that is the whole point...
but i agree in general that all DMFBs should have a 5" OLED on the back....
I'll gladly settle for the 11" OLED LCD on the back of the next generation MFDB.
Seriously, what I'd love to see would be a refined version of that IPaq approach, where the unit would be like a tablet, and it would run on its own rechargeable battery, and there would be maybe a six foot (extendable) cable that would connect the tablet to the back, similar to the VideoOut function of the Canon.
Yes, for many paying jobs, no doubt you'd bring a laptop or an Imac. But on some personal work, with no client present, you still might want to go out far less emcumbered, with much more freedom. But even then, I could see the need to really SEE what you're shooting. I'd gladly pay an additional five or six grand for this tablet unit. It would be small enough to be stored right inside the camera bag, instead of requiring a whole other Pelican case to be checked on the plane, like the laptop and related cables do.
I'm not a software guy, and I have no idea how large the Preview file would have to be, to show detail. I'm assuming about 900 pixels by 600 pixels at 72dpi, roughly, if it was a JPG document. What I also like is that the same company would make both units -- the back and the tablet -- so it could be thoroughly tested, instead of, say, Phase making the back, but Apple making the laptop, and then when something goes haywire, you don't know who's at fault. If Phase made both the back and the tablet, the testing could be done by one company.
I just know, in my line of work, there are MANY times when you're out on location, on a rocky mountain or something, and the last thing you want to do is drag around a laptop and Honda generator.
Just a suggestion.
