So what, that doesn't prove anything...
At one stage it said 950 has 2.1 & N9 4.0...
But now that doc says nothing about their BT differences.

just fyi
As opposed to RGB... you know this how exactly?

Thanks.

It is at least hinted in the release notes of the N950, there it is mentioned that one pixel stron lines should be avoided and they should be at least two pixels strong if targeting the N9. With Pentile you could run into visibility problems with such one-pixel lines...

I'm not entirely clued up on the differences...
Why's Pentile better than RGB layout for AMOLED, or is it?

Pentile:
http://en.wikipedia.org/wiki/PenTile_matrix_family and http://en.wikipedia.org/wiki/AMOLED
TFT (RGB layout):
http://en.wikipedia.org/wiki/TFT_LCD

edit: and as you can see from the photos a page back, I've access to both a Nokia N9 and a bunch of N950, so I know for sure.

I don't know which variation of PenTile matrix the N9 uses, but Ars ran an article on the Nexus One's screen that provides a good introduction to (one implementation of) the technology and of the pros and cons involved.

How does the overall experience compare to iphone 4? How is the email and does it support provisioning?

Thanks kozzi, zeh, & sjgadsby!
I'll read-up on the differences when I got a minute.

I still don't get how BT4.0 is now a definite though.
See my posts on previous page.

Polycarbonate products are rarely marketed as plastic. It's very high quality material and certainly much better and expensive than common commodity plastics.

Good heat resistance and by far the best physical resistance of all plastics. Some bullet proof windows are actually made of this stuff, but don't shoot your N9 (I doubt the shell is thick enough). It's resistant to most sterilisation methods and biologically inert making it ideal material for various bottles/containers/etc in my research work (microbiology). I've done some long term growth experiments with fungi that partilly dissolve most plastics and then die from released toxic compounds, but can't do anything to PC and thus live long and prosper.

Overall I would say good material choice for a mobile device. Light weight, tough, very durable against continous stress and for a plastic it also feels good in hand (ie. not that cheap plasticy feel of many commodity plastics).

Aren't CrystalCases too made from Polycarbonate? I'm already on my 3rd, because t some point all of them developed a crack. By the way, POM (Delrin™) is also very resistive. For example black keycaps are made from it.
