Well ... that is not so bad ... even if the fact that sd card cannot be

Yes that's the great thing about openmoko, and my intent was definitely 
not to shoot the messenger.
It's *much* better to know now than to find out.

Well, no, I'm aware of this. I really meant 100$ phone (without contract 
and carrier subsidising, and yes I
priced in the feature inflation til autumn when the Freerunner will have 
to compete with other phones).

Valid point, but as you said the Freerunner will not be able to play 
QVGA from the SD Card ...

Well I estimate that in autumn the Motorola K1 will be in that range, 
eg. It does not have WLAN, of course, and it doesn't even have
QVGA.

However I did not want to make a point about the openmoko's capabilities 
vs. such a cheap phone. *I* still think the freerunner
is worth every penny of the 400$.
I wanted to make a point about *consumer expectations*. And if even a 
phone like the K1 plays Video, people will expect a device of
freerunners class to have this capability.

Well of course not for the Freerunner (GTA2). And I'm very happy that 
it's far too late for that because that means I'm gonna have mine soon.
But for GTA3 this should be considered as an *very* important issue. But 
that should go to another thread then.

And again thank you for the detailed explanation of the really gory 
details :)

In a way that is great for my project that aims to develop a grid based

I'd love to see this, but as I'm not in the position to put considerable 
efford into this either I will just shut up
and not complain :)
