Hello, I'm considering buying a laptop to work(soft developing/maths:matlab,maple) but in the future I'll buy also a soundcard and use it as a realtime FX box (for guitar/keyboards,15-30ms of latency are enough and I don't need MIDI, I'll use softsynths). 1) What soundcard do you recommend me? For me it's not a problem to work a little bit more to win enough money but I don't want to lose my time finding and testing unstable or non supported drivers. Also consider that for audio work, most of my time I will be running M$ windows (linux audio isn't good enough for me) even if for experimental sounds Linux may be great. 2) I won't buy it now so what kind of things should the laptop have to have the possibility of buying an external card afterwards? PCMCIA, Firewire, USB2? Any chipsets/CPUs are preferable? I know this has been discussed many times here but since there's a lot of movement in USB/Firewire in the last days, I think that it would good to take another picture of the state of the art. Thank you very much in advance, MarC
