I 'dumped it all for a pod' a while back. I went with the XT pro and floorboard option. I had already owned the pod alongside my amp and used it exclusively for all my recording and home playing through IEMs. I think it was when I played a gig in Manchester after recovering from a back operation that I realised what a good idea it was. All I took to the gig was my pod, my IEMs and my bass. I got my studio sound live and could hear myself better than ever before.
It got to the point where my amplifier became a glorified personal monitor - the larger the gigs the less I needed an amp because all the audience could hear was the FOH anyway. The pod route worked as long as the monitors at the venue were up to it - not for sound necessarily as I had my headphones, but for a bit of 'rumble'. Without IEMs though I would be uneasy about using just the pod because more often than not the monitors at the venue are not up to much, unless or course your band has their own setup.
I sold the pod a while back for the Roland equivalent, the Vbass, and haven't been happier. I use it for recording and home playing and live through the PA, but I also have a bass stack with a poweramp which I can plug the Vbass into alongside the PA or any combination of the others if I need to, because sometimes only a rig will do.
It works for me and I think lots of people are coming round to the idea of such a setup in the search for lightweight solutions.
Cheers
