Quality rating is prone to individual bias.
Well, for nerds there will be projects similar to this one
or this one
I will come up with a DIY primer on how to cope with these way to lousy caps
Anyway there are ways to use the FR as a decent MP3-player without any mod at
all, for all but the most high-end-audiophiles.

No we HAVE an issue with decoupling caps in FR (simply too small and cheap).
However it depends on type of headphones used (impedance), and it's
absolutely fine for line-out usage, like connecting to the car, home stereo

Only (partially) true for usage with low impedance headphones.

Yep, definitely. I used it for MP3-player (with original headset), and it
wasn't THAT bad. Lower frequencies quite weak with low-Z-hs and on standard
EQ-setting. I'm used to $600-headphones, so I noticed this. YMMV. Stereo
anyway, so this is wrong info.

No, it's true, it's EMI to the mic. Probably you can fix it with a ferrite
block on headset cable near to the jack (well, not quite nice... but as long
as it helps. Not tested yet though - by me).

Our tests on GPS TTFF where quite comparable with some of the best devices
available. However note there is some data GPS *has* to download from sat
for "virgin" fix, which may take as long as 12min due to low bandwidth the
sats offer (just takes this time for them to send one complete set of ephem
and alm), and this download needs signal 30dB better than that for mere
position fix. On tests done at Taipei the TTFF was around ~40sec without(!)
So this is a clear sw-issue.

Dunno whether Carsten and Mickey consider it worth to answer this. If they do,
it'll make may day ;-)

So what. Everybody knows. Never anybody stated anything different.
To me he looks quite trollish.
