Wth all due respect, more buttons is hardly fundamental/technical. In fact, with a reconfigurable display, (think iphone) the buttons might be even more convenient in a cell phone.
This is mostly optics. Short shutter lag is not fundamental. It is just related to power usage.
ASsuming OVF means optical view finder, surely you don't consider that fundamental? But I agree it is not normally found on cell phone cameras.
This is already covered in 2. I have always found it difficult to shove a telephoto lens into my pants pocket.

Many cell phones (of the near future) are moving away from a ssytem on a chip (SOC) approach where the image processing is done on the image sensor, and instead, a secondary processor used for image processing. That would include AF and exposure. The memory goes along with that, and its cost is always dropping.
3. Because the bride will shed more tears if you shoot her wedding pics with a cell phone than if you shoot Bambi with a pistol.
Glenn, that is funny, given my background. I was hoping to uncover some fundamental issues from the brain trust out there.
If someone thinks a cell phone beats a DSLR, they need to check out something like the 11x14s, 13x19s, 16x20s and 20x30s I've got around the house, all taken with a Pentax *istD.
Yeah, I do consider it fundamental. It is the result of the camera being an SLR. It gives a direct view of about 95% of the scene shot. It doesn't pixelate.
BS. Bigger optics=wider optics? Or anythiing else you want it to. Nuts to that.
That seems to have no bearing on the previous statement, which concerned 'the majority of consumers'. I think it's safe to say that someone who refuses to get a cell phone is not a majority consumer.
Which may be something of a shame. Tried it. Don't like it.
OK, I agree.
I added an extra zero to each of your numbers (e.g. 150mm). Can't explain why my brain did that. But anyway, this still goes in the category of better optics for DSLRs. It is hard to get a decent lens made for $2, even at 3 or 4 elements.
I'm not sure video mode design and DSLR still picture design requires some trade off although it is true that large pixels imply large capacitance which implies more power. DSLR designs do not usually have on-chip ADC so perhaps this is part of a trade off. It is harder and requires more power to get high res. ADCs to run at video rates, although 30x100k pixels = 3 Mpix/s is hardly video rate.
So, you are thinking less dark current I suppose. Camera modules inside cell phones dont get that hot, but hotter than a DLSR I suppose. Unless that special black body is sitting in the sun....Anyway, dark current is not important for many apps, and can be subtracted out in many others.
Heh. This is part of the optics issue I guess. I thought oyu were going to say something else. Like, drop your DSLR onto concrete and kiss it good bye. Drop your cell phone/camera phone and complain about the finish being scratched....
If cell phones replace some lower-end cameras, I see that as a good thing. I would hope that buyers would be less likely to think that their cameras are "equivalent" to higher end; and thus may actually be more-likely to "purchase" (high-end) photography.
