Yeah, it's surprising. People forget the that the sensors in a camera do not sense RGB directly, only monochrome light levels. Each sensor has a R, G or B filter over it. Because of this the sensors are arrayed in a pattern of R G and B like:   R G B G R G B G G B G R G B G R    (I think it's the G cell that for some good (but easily forgotten by me) reason is gets double representation.)   So the RAW file has a 12 or 16 bit number for each cell. In camera post processing...
  Thanks. Conciseness has its price though. It took me much longer to compose my concise answer than it took you to write  a similar longer one.   
While most of what you say is right on, it's deceptive to say that the TIFF file is not compressed since  a huge amount of the RAW image data gets interpolated and tossed out during the post processing of the TIFF. Ironically an uncompressed TIFF file is usually larger than a RAW file since it has uncompressed RGB values (no alpha unless you add it later) for every pixel while the RAW file has only one value for each pixel (sensor cell.)   TIFF: each pixel has 8 bitsof...
• All cameras 'shoot' RAW. They just don't all output RAW files. (which is why many cameras have been hacked to output RAW files.) • Compression has nothing to do with RAW or not RAW. If all the original sensor information is preserved, untouched, compressed or not, it is RAW data by definition. • Enhancement of any kind that irretrievably changes the RAW data makes it not RAW.
I'm a product designer, not a graphic designer. Not really a common design term though. Only people instructed in photography seem to know the term. But I'm also a terrible speller. I like photography though, so I should know better. I know it's a Japanese word and blow the spelling (maybe it should really be spelled  "Boka" as it is in Japanese?)  
  Not to be a noodge, but the very first words of your post, "proof reading" are properly written as one word. Otherwise, I agree with you . . .   It's just funny how it always seems to work work out that way on proofreading complaint posts.   ;-)
 It is in fact a very dense sensor and not up sampled as one might have assumed.   Amazingly the whole darn lens (not just a snigle element) is moved to correct hand movement as sensed by gyros. It's pretty cool. I was also surprised.
  Yeah, Nokia is doing some interesting things with the camera. I applaud them in that I often wish I could have a bit more control over Apple's cameras. Although most people probably don't care, its good to see Nokia doing some interesting touch screen UI work for camera controls. (It seems nobody else in the space is doing it.)   BTW, the problem small sensors is too much DOF (no Boka!) not a lack of it. But I assume this is what you meant. :-)
  One might look at Nokia's oversampling and and Apple's HDR approaches as two somewhat diverging methods of moving toward the same goal. The oversampling strategy pursues dense spacial sampling while HDR pursues dense exposure sampling. Both record extra information in order to produce images with better signal to noise ratios.
  Hate to break it to you but "it"  hasn't been "a cellphone" for many years now. What people are buying now, despite refering to it as a "smartphone," is actually a "pocketable, networked supercomputer with a variety of environmental sensors," including GPS, camera, compass, gyros, etc. And they are buying them to meet highly individualized needs of all kinds (they don't limit themselves to your imagination.)
