Everything for "normal" laptops applies, PLUS more on the hardware side!
I realized this after fighting with the PCMCIA slot sof my laptop to get
my HDSP soundcard working for the better part of this year [on and off].
RME-audio [makers of Hammerfall systems] has useful [although not always
totally current for newest models] info about different laptop models,
as well as a list of things to watch out for. This like:
which chipsets perform badly for audio
why you should avoid shared-memory graphics chips
info about USB bandwidth and audio dropouts
Worth a look even if you can't shell out EUR 1K for an HDSP.

also valid for audio laptops. As most (all?) laptops don't provide
high quality, let alone multichannel audio, you will have to use an
external solution most probably.
