If you're looking for low latency, than you're propably looking for the
Linux rt-kernel. The generic kernel already does low latency very well,
but the rt-kernel can be a level higher.
Don't know how much the hardware is relevant to the choice of a distro,
other than that of my own experience with NVIDIA graphic cards, in which
case I've come to believe that NVIDIA works easier on on "Ubuntu"
RT-kernels than on much of the competition, unless you compile the
kernel module yourself. Specifically in RT-kernels the difference may be
striking.
I've tried Fedora withPlanet CCRMA, last autumn (on Pentium 3 and AMD
Sempron), but had to give up after loosing two harddisks at once (on the
same machine). I seemed to have problems with something to do with
no=acpi, or something on that road (I'm not a wizard at these things, as
you may have gathered). I made some extensive research on the subject,
but the solutions given on different forums were not enough for my
hardware, at least. Shutting down didn't work very well. Often I had to
use the Power button to shut the whole thing down. This was on a clean
Fedora + CCRMA system, with no other additions other than:
a pci usb 2.0 card (which may have caused the problem due to IRQ, if I
understand correctly)
a pci m-audio sound-card
and a pci wireless network card.
Puredyne uses the "Ubuntu" RT-kernel, to my knowledge (it's been a while
since I updated that machine),
That is the system I use as a "production machine".
The pre-installed Pure Data did not work for me. Neither on the 32 bit
system or the 64 bit system. The input sound was not right (distorted,
wrong samplerate, somtehing like that).
However, the daily build of pd-extended (at this date being the release
candidate 5 (rc-5)), works perfectly. And the Ubuntu RT-kernel, together
with the minimal Puredyne, XFCE desktop is a dream for the live musician.
It "just" works for me.
At home, when "rt" is not as important, but easy desktop-use is, I use
the standard Ubuntu (though not crash-free).
Can't find a straight answer to which is the best system. I haven't had
stainless experiences with any of them.
99% of the time, though, I prefer Ubuntu-based systems.

for sure which distro will work fine on your computer, but there has
to be one. Just be patient!
(Slightly off topic) Just in case, i'd recommend downloading and
burning Gparted Live and Super Grub Disk before you start
experimenting with various linux distributions. They'll come in handy
when it comes to formating your linux partition and accessing Windows
again.
Also, when you have a linux distribution installed, first thing you
should do is download and install the realtime kernel (when
available), and then try JACK to see what the minimal latency is. If
it's not way less than in windows then there's something wrong. Then
download, install and run Pd, and make sure it works normally (it
didn't in Ubuntu 9.04 on my laptop).

Thanks guys, i'll definitely be looking at your suggestions, i
think it's pretty clear that i should make the move to linux, but
i just haven't gotten to it. i already have an acer netbook, but
the issues there are horrifying latency and breakup of the sound
(at least on windows), pierre's solution seems like my ticket for
now, as i don't need to have the system on me. although the
bisquitbox, audiopint , beagleboard ,etc. seem like good
possibilities.

I suppose that by "exclude" you mean you want to avoid interacting
with your laptop directly?
I don't know what platform you are on but you may want to consider
using a netbook. It gives you more power than a beagle board,
you can
develop/test your stuff right on the thing, it is small and
you could
even fit it in a small backpack that you could carry on stage.
If you
are familiar with linux you should search linux-audio-users
list for
some info about getting it done. Ivica Ico Bukvic (who is also on
this list) does a laptop orchestra with netbooks running
linux, Ken
Restivo uses an eepc for live shows as a softsynth and DSP
(IIRC) and
I was recently involved in a project where a mobile setup with
netbooks, speakers and microphones was used and carried by
musicians
