I'm thinking of buying a laptop for live use, just to run Ableton Live & afew audio/midi loops, so I shouldn't be needing anything too high-spec. However, most of the laptops I've seen in my price range have seemed somewhat limited in terms of soundcard options. None of them had firewire ports, so am I right in guessing that if I want a decent audio interface I'm going to have to use USB? I've never really read anything positive about USB cards, so I'm kind of reluctant to get one - Is it possible to get a firewire port installed on a laptop?, If not, are there any other solutions? Finally, if I am forced to go with USB, what problems am I likely to encounter & how can I go about minimising them? And whilst I'm asking, can anybody give me an idea of how easy (or not) it is to upgrade a laptops memory? If a machine has, say, 128mb or ram, can I get it up to 256 by just adding another 128? Or will I have to replace the original 128mb with a single 256mb stick? Cheers bluds.
