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 etc etc Worth a look even if you can't shell out EUR 1K for an HDSP. http://www.rme-audio.com/english/techinfo/index.htm good luck, d.
