Hi Rask, thanks for your answer, especially the part with the battery
i think i didnt express myself well enough there. i'm not expecting a well
polished phone. i'd rather buy an openmoko for its openness and incredible
range of possibilities (due running linux). As i said, my main concerns are
battery power and acceptably reliable phone functions, which are for sure
software issues and will be fixed hopefully soonish. But, on the hardware
side, there still is the buzz, which can't be easily fixed through software.
Thanks to Wolfgang for giving a short and nice view, of what the future may
bring. i enjoyed reading it and it made me a bit more wanting to have a
gta02 soon instead of a gta03 :)
Thanks to arne for answering fast and making me a bit more willing to get up
one hour earlier to have my phone fully charged when leaving the house.
ps: ya i got an alarm clock, i rather meant that there are power strips,
which will turn on at a certain time. i could configure those to start
charging my phone at 6 am, but actually i'm not willing to :)
thanks to michael and hendrik for giving me some user reports and references
on battery life. it's nice to know the "FR" can make it to 3 days, although
on low usage.
and especially thanks to sarton, who was not only telling me to get this
phone or not, but also gave a somewhat realistic opinion on some doubts and
things that won't work up to now or for rather unadvanced users.
You somehow made me not wanting the FR as my first phone, but as a second
phone + testing plattform with which i could have fun, as long as this isn't
my only phone in certain circumstances.
Relating to this thread  the buzz fix will be applied in A7, which will
hit the shops pretty soon.
I think you guys didn't totally convince me that the FR would be my first
phone of choice at the moment, but you dispelled my major doubts about
battery power and software usage.
Now, as the buzz seems fixed, i think i will get this phone in march or
something. I'm having a second sim card i'm hardly using in an old 6230 at
the moment(maybe also its battery could be of use :) ), with which i will
use the freerunner as a second phone for now, until the sim card gets
deactivated (decembre 2009). Until then i hopefully will get used to it, and
the phone will get used to me. I expect the software to become better until
then, phone functions as well.
i guess it will help me creating tracks for osm, listening to music on the
go, reading some news in university and last but not least diving deeper
into linux in general.
you guys made me like the community already 2 months before i'll actually
get the phone and i hopefully will have a lot of fun with my FR and with
you, the community.
Maybe i could also help the community a bit through bug reporting or even
some translations hehe (since i'm not into coding at all :) )
PS: thanks to sean and the team to keep things running, having YOUR own way.
keep it up!
best regards and many thanks, tschaka
