What you say is absolutely right. But it seem that Nokia is actually the
number one on this planet regarding the mobile phone market, so there
are probably not talking about small quantity...
In a more macroscopic view, I can't understand why Nokia buy a software
company like Trolltech to get a technology and still rely on externals
chip manufacturers for there very really central technology of almost
all there business.
If Nokia manage to get enough control of a chip maker, like there did
for Symbian for example, there can open enough the needed interfaces to
let there OSS strategy grow.
My personally think that maybe the solution is a chip that have two
parts. One part is a on the edge proprietary wireless processing (BT,
3G, WiFi, etc..). The other part is a OSS well supported general
processing. The parts must communicate via a well documented interface
of course. The split between the two parts can be different, I just give
a big picture. The main point is that the proprietary part must not
depend on any Open Source software, and this last one must see only well
documented interfaces to do all the programmers reasonably wants to do.
