I guess it depends what you are using it for, but 10ms from pressing a keyboard to getting a note out is not so bad at all - within the realms of analogue organ response times, I think.. If you need to feed audio in and have near-zero latency, that is a different matter.. For my live setup (virtual synth-rack) I am planning to rely on the internal sound - at least in initial (rehearsal) tests.. Not too worried as long as latency is <25ms and xrun-free. >>For live work, Guitar effects, soft synths, etc. USB 1.1 at 16bit/48k may >>work just fine > > My experience with USB audio is limited, but USB 1 on mac, for live > processing, I have found to have unusable latency. > Latency in 1.1 vs usb 2 shouldn't be significantly different as I understand it. usb 2 just allows higher bandwidth - so more channels or 24bit vs 16bit.

Yes - I just got a scarlett 2i4 and heartily recommend it - although haven't stress-tested it much yet. Quality seems very good! Be careful though - not all usb2 devices are supported in linux.. Re: firewire - there was some discussion here a year or so back that it might be being slowly discontinued - fewer laptops having as standard etc, and most consumer interfaces moving to usb2.
