Not sure, but I believe it has 65000 colors.

What wireless chip is included in 770? Are you using devicespace
stack? Is wifi driver opensource?

It is similar to other 'open-sourced' drivers - binary firmware, open
source driver.

Anyways... this is getting off-topic. Sharp Zaurus was great hardware,
but its not shipped in USA/Europe anymore.

And if the only criteria for hardware-that-matters is hackability, then
Nokia 770 can be flashed with your own kernel and rootfs. Check
www.maemo.org

Ok.

Agreed, this is getting off-topic.

I agree that Nokia is doing the right thing (tm) here (and
THANKS!). (Excluding charging circuity, but someone is going to fix
that). Unfortunately Motorola is not doing the right thing...

Could you perhaps provide list of operating points for 770? It would
help understanding a bit, I'd say.

Note that the 770 doesn't talk to a public network, over regulated
frequencies and power ranges, and isn't constrained by, for instance,
the GSM standards, and they're not constrained by the requirements
of middlemen (carriers), so it's not really an apples-to-apples
comparison.

That said, I do respect the way they have been working directly in
community projects.

Yes, 770 is in easier position...

...still, publicly downloadable SDK for userland software on
a1200/a780 would be nice. I do not think userland software can break
power levels/frequencies, so you should be okay, and symbian /
windowsCE certainly solved that problem before you...

To sum it up "it is nice that motorola uses linux, but you could do a
bit better".
