It's been fine for me so far (reliable enough for gigs).  Jack latency 
is 10.6ms, can't remember the frames/period for that off the top of my 
head.  The response is fast enough for keyboard playing and live input 
processing.  To get that without xruns I had to use a fully-preemptible 
kernel.  I'd recommend it for getting sound in and out a laptop.
