Hi,
I would like to buy an external audio interface (mainly for a laptop,
but I may use it with my desktop machine too). My requirements are:
- must work with Linux (obviously) and MacOSX,
- at least 4 inputs, 8 would be better (for recording drums among
other things),
- at least a couple preamps would be nice, but this is not an absolute
requirement.
AFAICT, most USB interfaces have only 2 inputs. I found the Edirol
UA-101 and the Lexicon Omega Desktop Recording Studio which look like
what I want, does anyone have any experience with these two?

Nothing is known about the UA-101. The UA-1000 is partially supported
(playback doesn't completely work). If the UA-101 is similar, it
requires an addition to the driver before it will work.
The Omega seems to be supported out of the box.

USB interfaces
I would stay far away from USB and audio;). It can't offer any
guarantees for realtime audio and is unsuitable for serious work, in
my opinion.
How are users experiences with this?. What latency are you running at
with your USB hardware? (a stable one without dropouts no matter what
the load).

8msecs latency. the lower combinations of buffersize and -count
(always dividable by 3) don't work with my 3-year-old laptop and
USB1.1...
If you want to be mobile, go for usb i'd say.

Oh wow - any word on reverse engineering the MOTU stuff? Years ago
they already had pretty cool looking 8+ analog I/O firewire boxes that
I sadly turned away from.
Google didn't turn up anything obvious ::-)

if you were using ieee1394 for audio "years ago" it was either mLAN or
some utterly proprietary
Google didn't turn up anything obvious ::-)
there are currently 3 ways that ieee1394 can be used with audio:
a) proprietary protocol on top of ieee1394 (e.g. RME
Firewhatever, MOTU, RME hdsp)
b) the BeBox chipset and protocol
c) mLAN
b and c (and possibly (a) but how could we know?) are definitely based
on IEC61883, but have extensions to cover things that IEC61883 doesn't
cover. Bridge Co, the BeBox makers have apparently tried to feed their
extensions back to the IEC standards body. yamaha are still playing the
"our toy" game with mLAN for the most part.
there is no support for (a) on linux (the hdsp is supported because the
use of ieee1394 is transparent to the driver - it does not plug into a
generic ieee1394 interface).
there is no (actively growing) support for (c) either, despite the fact
that yamaha keep saying they are OK about an open source mLAN
implementation. they still do not appear to have released info on the
parts of mLAN that are outside the IEC61883 specs, making any support
based on that standard pretty poor.
the freebox project supports all devices that use (b), and such devices
can also be physically chained to produce larger meta-devices. the
project has reported success on linux with a number of devices.
if you see ieee1394 h/w advertised, bug the advertiser to say which of
these technologies they use. forget linux - just tell them you are
interested in chaining the device with existing ieee1394 audio h/w that
you have, and you want to know if the advertised device supports it.

How about an echo layla with the pcmcia card? enough inputs and
supposed to work fine... though i'd check from someone who actually
has one. I was looking at one for a bit but decided buying a new
machine (desktop) was a priority, as i don't really need all those
inputs. http://www.echoaudio.com/Products/CardBus/Laptop/index.php you
can pick them up on ebay, as they have been discontinued, in favour of
firewire.
