Hi all,
        as others have already pointed out, with the
solid state / HD recorders and the memories we
have now, a dedicated recorder is much much
easier and reliable to run in the field than a
laptop connected to a sound acquisition device.

Although, I'd use a laptop or maybe a handheld if I need...

1 - real-time visualization of the sounds I'm
recording.... ultrasounds for example...
2 - to record for days and days with big batteries and solar panels
      (I prefer to leave unattended a 600=80 laptop rather than a 2400=80 S=
D 722)
3 - scheduled recordings....
4 - triggered recordings....  recordings that
start when a special event occurs or when
acoustic energy in a specific frequency range goes above a threshold...
5 - georeferenced recordings....  for example
when I record marine mammals from boats or ships
6 - multiple channels....  in such a case I love to use the MOTU Traveler
7 - accurate level calibration

In all the above cases I use my own softwares:
SeaRec, a multichannel recorder with scheduling
capabilities, or SeaPro, a 2 channles real-time
visualization software with continuous recording,
georeferencing, and smart trigger capabilities.

Anyone interested in testing or using those programs can contact me private=

In the near future it would be nice to see pro
recorders that incorporate a smart timer with
multiple scheduling, a level calibration system,
an integrated gps, and maybe a simple spectral
display to immediately verify the presence of strange noises...
...maybe for the next Christmas ?

A Merry Christmas to everyone and my best wishes for a wonderful new year,
