Theoretical discussion about CCD / CMOS
 
I changed the title, the first post has also become redundant so read from post #3 on...


Camera (pro)
8MP instead of 12MP? I dont care, quality has in this case nothing to do with
higher MPs.

Admirable effort but we dont really need another thread. A little tired of seeing so many N9 one's pop up.

No disrespect to you.

No doubt, i like it! 3.9" is a very good choice, everything smaller than that would be a drawback as of the software kbd.

Note that the quoted 3.9" diagonal is misleading. The screen is about the same height as the N900's, just a bit wider. So if you found the N900 screen too small (I know I did) you won't like this either.

Actually it does, higher pixel density means lower quality.

Fixed that for ya ;)

If the estate of the ccd sensor doesn't increase at the same rate as the MP than it usually means LOWER quality, because it gets less photons per pixel and you get noise, esp in lower light environ.

Meh. It's got Swype, and I should probably start learning to use an on-screen keyboard. The world isn't gonna wait for us to be convinced of a technology most other people are happy with.

CPU/GPU (con)

Can't get behind this one. I don't need my phone to have specs that only a small nuclear power plant could power for a day on. Harmattan looks snappy on the hardware, which should be enough. Good hardware design is about more than just specs.

Battery (con)
Again, this is a trade off between good design and practicality - and I must say my phone battery only leaves its' slot when I've botched something and can't turn the thing off.

As you can tell, I'm pretty impressed by the N9. The keyboard is a disappointment, but I think it's time I accepted that touchscreen keyboards are a big part of the future of phones and tablets - and started to learn how to use them better.

Exactly. Ye canna change the laws of physics, Cap'n!

Have you been drinking a bucket of Jobs-ade? A good big CCD is a plus, granted - a large 5MP CCD might outperform a smaller 8MP CCD, for example - but more pixels are also a plus. like for like, a higher pixel count on the same sized CCD wins out. Don't make me get out my citations ;)

I don't even know if you are joking or not, if not could you please explain since the idea I have about sensors, pixel count etc seems to be wrong.

no he hasn't, because in phones we aren't offered bigger CCD's, we are offered the same tiny CCD with more pixels, which means proportionally more sub-pixel grid, which means less surface area to collect light upon.
