There are hints that voice will be supported by Maemo 5 to some extent; my guess is primarily via headsets (either the wired one already included or Bluetooth preferably).

At a push, it may also support the headset-less "speaker phone" mode you can currently use with VoIP, or even sideways-holding-to-head.

I'd be surprised to see the Maemo 5 device(s) marketed as phones, and sold through normal mobile contracts though.

Or presumably they don't want to let people play with voice on an open device.

So far they confirmed only data support (not voice) for upcoming device and Fremantle OS version. Presumably voice will come later.

That'd be great. Possibly the only thing missing for me to buy a Maemo tablet.

Nokia's Maemo uses telepathy (it was the first to deploy a Telepathy-based client with libjingle for GTalk audio support, as far as I can tell), so this might actually explain why FSO is not being reused.

The next-generation Internet Tablets will finally have GSM/3G capability, so my guess would be that oFono is meant specifically for that purpose: giving Maemo in particular (and GNOME Mobile in general) a cellular stack that integrates well with other standard components.

> maybe Intel has some new embedded CPU's that I am not aware of

I am told that Intel sales reps are trying to sell Atom to people who are currently using XScales. This is not really a "drop-in replacement", to say the least.

Of course a lot of the XScale technology went to Marvel, who seem to be doing more with it that I had expected (though they don't seem to get much publicity). What I'm not seeing yet is a replacement for the XScale chips with PCI, or some alternative way to get a high-bandwidth connection between a processor and an FPGA; the choice seems to be e.g. PCIe, which is hard to do at the FPGA end, or some sort of slow flash memory bus.

'StrongARM seems to be "dead"'

Intel sold strongarm (renamed XScale) to Marvell many years ago.

Well, considering that openmoko re-invented their telephony stack three times, it does sound slightly hypocritical to complain about others being NiH..

FSO already some overlap with telepathy (I wouldn't say NiH as a big percentage of FSO is gsm-specific which does not exist in telepathy), so it would also be interesting to hear how telepathy and oFone compare/overlap/co-operate.

Specific quote from that link:

<holtmann> Since it is a popular request to compare FSO against oFono, we will be working on writing up the details they have in common and where they differ.

Intel is preparing for the x86 based SoCs that we'll see in the years to come. You'd be surprised how much they'll be pushing in the direction of getting their foot into the mobile market, given the quantities in it.

I donno. StrongArm is probably the most convient platform for them to do development with. If it's actually Intel putting work into it then they probably have toolchains and development machines setup for other purposes already. Just pull them out of storage and there you go.

Otherwise I expect that they are coded to be portable and all that, seeing how Intel is more and more interested in x86 on handhelds and whatnot.

Actually this seems to follow the same philosophy as FSO as you said: D-bus based approach, and nothing more than a framework. All higher-level stuff vendor-dependant.

I wonder why they don't support FSO instead. And I can't see how Intel fits in at this point - StrongARM seems to be "dead" and other manufacturers have much more attractive CPUs (price and performance wise).

Or maybe Intel has some new embedded CPU's that I am not aware of.

So no more Windows Mobile, nor Symbian ? Strikes me as odd too. Intel seems to be drifting away from Microsoft lately. But something tells me not to believe it.

I wonder how this compares with FreeSmartPhone:
