No way you are getting a Black magic running for the list price, that camera is near unusable out of the box. The fact that you have to format the SSDs with a mac filesystem basically means it would be unusable in a PC workflow.
Your statement about using it on a PC is needlessly over the top. I've been taking a serious look at the BMD Cinema Camera for a couple of weeks now. I actually pre-ordered one, but I might cancel before it ships (I figure I have a while to wait). I am in a PC-only environment, so I'm taking seriously the workflow issues when considering this camera. But, being on a PC isn't one of them. You don't need much computer know-how to be able to use a Mac formatted drive in a PC environment, especially for just retrieving footage.
Your main point - that $3000 won't give you a camera that you can take out of the box and start shooting with - is correct. But, let's add it up: Macdrive (Windows software to format a disk in Mac format) is $40 (available as a download). An SSD runs in the $200-$400 range, depending on capacity. SSD dock? Mine just arrived today (I decided I needed it to do more backups anyway): $50. Rig? Maybe. I'm looking at a simple handle so that I can hand-hold it. That's another $50 or so (you can spend more, but if you do, you should add the same to the C100). An external battery: $300. What are we up to? About $4,000 (that's overestimating). I could almost get two BMD CC's for one C100.
The points about resolution may or may not be valid. I think it remains to be seen as to which has a sharper image. The images from Mario at OneRiver are quite detailed. Should we discuss dynamic range and the power of shooting raw? I think anyone on these forums from the stills side understands the benefits of raw vs. a compressed image. If you want to shoot a quality codec where you've nailed the white balance and exposure, fine. You can and have tons of space with a codec (actually, a choice of them) that is far superior to that of the C100.
Crop factor. Yes, definitely a benefit of the C100.
I suspect that a lot of people will make a good living with the BMD CC. Same can be said of the C100. Beauty is, we both get to use our nice EF-mount glass!
