I use the freerunner as may daily (and only) mobile phone. I use the SHR
distribution, image dated 16.dec. This is stable, and several
important features work well:
* call and receive calls, get a log of missed calls.
* send and receive sms. (Some problems - you can only send sms to a
number, not a contact. But this is being fixed. Also, you can't
receive more messages than will fit on the SIM card - there is
not yet message storage in the filesystem. My SIM card seems to fill
up when it stores 10 messages or so - but no big problem for me.
* gps, mostly for openstreetmap. This works really well!
* playing music. Some tweaks to a config file, and this part works well
Things that are cool but not so much used:
* Accelerometers. Openmoocow is great for showing off. And I once used
gwaterpas to hang a picture straight.
* Voice navigation. Works, but I use the maps mostly to find places
that aren't mapped yet so I can improve them.
Stuff that doesn't work well yet:
* Wifi. I can connect at work - and speed is much better than usb
networking. But it dies after an hour or so - and don't come back
until reboot. It doesn't work at home at all.
This may be better with a newer kernel, but newer
kernels needs a newer version of the distribution - which hasn't
stabilized yet at this moment of writing. Or so it seems.
* Suspend. Well, suspend works, and the phone wake up if called. But it
doesn't bother waking up to process an incoming sms. And the gps seems
to be broken after suspend - so I don't use it. This obviusly cut
battery time for me. Newer kernels are expected to be much better,
and wakeup on sms will probably happen. (When suspend is needed,
reboot in order to make the gps work again.)
* Games. Not that important, but can be fun. But most games are kind
of laggy, responding too late. Maybe the slow graphichs is to blame,
maybe upcoming "accelerated xglamo" will help.

This might be a problem. The phone can last a day even without suspend -
if it isn't used much. It gets better if you let it suspend. But hours
of music will simply use up the battery. :-( It will last a few hours
with the gps on too, the gps eats power also. Don't know if the gps
itself is power hungry, or if it is the simple fact that it wakes the
cpu each second to report location. (And me spending too much time
looking at the excellently displayed maps.)

The phone works for me because I can charge it everywhere. I have a car
charger, most cheap "usb car chargers" will work. There is a web page
with a list if you want to be sure you get a good one. This so I can
keep the gps on on long trips.
At home and at work I connect the phone to the USB plug on a pc. I
hardly every use the supplied wall charger because there is usually some
pc available and the cable is easy to carry. If the pc is prepared for
it, you get flawless (but somewhat slow) networking through usb too. If
the pc aren't prepared at all, then it will still charge the phone.

This is only a question of programming - definitely fixeable.

Echo is fixed in software, the buzz must be fixed with hardware. You may
wait for the release of a buzz-free gta02. It will probably not be long,
now that they have published a buzz-fix that they can apply in
production. Or find some way of having it fixed. An electronics repair
shop or some friend good at soldering. Universities are not the worst
places for finding such people.
Or just live with the buzz. It won't necessarily be a big problem. You
won't hear the buzz, only those who talk to you. And it is most likely
to hit in areas with bad gsm reception, because that is when the phone's
transmitter have to use full strength to reach the nearest base station.
If gsm coverage is good, maybe your contacts won't notice the issue.

Sounds like you ought to wait for a7 or whatever then.

I have no problems with these things. They are stable in SHR. There are
a few odd user interface problems, but they seems to be fixed in an
upcoming release. Such as "no sms to contacts, you have to type the
number", and the way you actually have to erase the text "type your sms
here" when writing a sms.

I see no problems with reliability. The user interface can use some
polishing here and there, so we need fewer screen presses. But this is
being done all the time.

The phone isn't lightning fast. But I mostly wait for apps to load, they
tend to be ok after that. It is possible to play duke nukem with decent
framerate in 320x200. Any operation that demands less from the display
than that, _can_ complete in quite reasonable time! That doesn't always
happen, but improvement is possible.

You can wait - but it could be a long wait.

You can wait for the buzz-free phone, probably not that long.

I don't think this phone aims at "John Doe". He may see it as an "ok"
phone when all problems are solved, but still not that special.
It aims at various other people. Some want the openness and freedom from
vendor lock-in. (Don't have to pay your gsm provider for ability to
transfer mp3's from pc to phone.)
Some like the ability to install just about any software imaginable. If
you want something "unusual" on your phone, then you simply can't do it
with most others. Some can run java stuff, but lots of software isn't
java. Someday, someone will manage to update openstreetmap directly from
the phone - without going via a pc.
Some like the ability to hook up unusual stuff to the usb connection.
Anything with linux support will work - and that is a lot. You can print
directly from the phone, or use it to test printers with no need to boot
up a pc. Hook up a scanner to send a mobile fax. Connect a usb converter
to read (and change) the state of car engine electronics.
If there is big market for some new use people put the freerunner to,
then other phone makers will pick that up. I guess that the freerunner
and later phones will end up filling a large number of niches, where it
will be more convenient to bring than a portable pc. Or where gsm
functionality is part of the job.
