All I can think of is that most all the PC notebooks out today with Intel 
duo core
processors have the sound integrated into their motherboard with the 
rather than a separate "sound card". It's their integrated HD (high 
audio, and I can say at least that the output is superior to other prior, 
sound cards in PC laptops. I'm not sure about the input, but in my case it
sounds pretty damn good with the "ASIO for All" driver.  The standard 
sounds like crap, but this is no reflection on the hardware. I think this 
there is a lot of confusion. A poor driver can make just about any piece of
hardware (external or internal) sound bad. That being said, theoretically, 
can't tell any difference between the small cardbus Indigo unit and the 
HD audio of the ThinkPad...it's all just hardware and software, and the 
of the integrated audio is that there is no intermediate device (the 
and its
transfer rate)...I have to believe that the speed of the transference of 
data on the
motherboard for the HD audio is much faster than the cardbus.

Gotch ya.
