Hi Nikolaus,

thanks for the fast response. This is getting close to what I missed.

Definitely big thanks to Radek! (I think I should give QtMoko a try on
my GTA02 again too. At the moment it's running SHR.)

I don't think about a detailed table like function x works best with
kernel y. I think more about a table
like "there is at least one kernel / rootfs / bootloader" where function
x is proven working. Of course it takes time
to have full working distribution but thats another topic. Just about
removing fear.

We don't know exactly how the WiFi/GPS/BT/UMTS sensitivity compares to other devices because we have a so low number of devices to test. And the same is for audio quality (which largely depends on what we expect - and everyone has different expectations).
Agreed. My definition would be "good enough that the other side
understands me". But here it could
help that those that have a device just tell what they experienced. Same
here, remove fear of getting something
unusable. The more success information is spread the more people might
buy one.

Hmm... I never coped with UMTS/GPRS/GSM stuff. But I did PC BIOS
development for some years.
I think at least I'll have a look at the UMTS module's datasheet. But in
my case spare time is the biggest
issue. At least at the moment.

And don't forget Augustiner Weizen!
