A hypothetical n950 might be nice if it happened,
but Nokia has just flushed the final dregs of credibility down the drain.
They could say or announce or even demonstrate anything they
can dream up and cobble together, but it would remain uncredible.
Who can trust Nokia ever again after the betrayals they
have repeatedly performed against their most ardent fans?

Anyways -
i am actually building my first replacement prototype for
my orphaned n900s now.

a bit rough,
but I am starting with a mini-itx board.
specs:

core i5-650
8gb 1600 ram
Corsair Force 240gb
12vdc power supply
Huawei telephony (usb)
still not sure about the screen yet - but prefer resistive.
will run Mandriva with Debian (and other guests) in VM.

and no -
I really do have a need and immediate use for such a beast
my occupation is weird and it gets weirder every year.
(data acquisition with 64bit processing)

Others can keep their candy-@ss candroids
their apple prisoncells and their m$ virus-fests,
I will have open-source, mobile and on steroids thank you.
