Once again, there is no competition here. Not everybody has the same
time and resources, level of technicality, etc.. Not everyone has the
same goal. Maybe some people just want to have a fun hobby learning a
bit more about GSM, reverse engineering, etc. ?

So what? None of the mainstream operators are using network-side Osmocom
components, but still they generally work, and some smaller operators have
been running them very successfully so ;)
None of the mainstream IT companies were using Linux in the mid-1990ies,
still it was quite capable back then.

Did it occur to you that Fernvale had completely different goals?
Also, how long do you think that your "commercial quality" modem will
continue to be available, given the ancient, end-of-life components it
requires?
MTK still produces newer baseband chips with GSM/GPRS support, and from all we
know they didn't significantly change that 2G part in ages. Why would they? It
just lives next to their 3G/4G modem parts, probably copy+pasted from the older
designs.

Please stop that negative attitude. Nobody needs any realistic plan if they
want to play/hack around.

Maybe it's you who is out of touch with Craigs reality? I think Craig
is quite realistic when it comes to his ability to create a "production
ready GSM/GPRS modem". But did he state anywhere that this is what
he's aiming for?

Please respectfully leave it up to others to make whatever judgements
they want on how they spend their spare time. We're not telling you
how to spend yours either.
Having said this, please feel free to share your points of view in a
neutral way - but don't be judgemental and/or attack other people just
because they are doing something that's not according to your taste,
or which you think is inferior.
