Steve, I have been using amp and effects modelling apps for quite a while with my iPad. I use iRiffPort as an interface which, though expensive, is far superior to the interfaces that plug into the headphone socket, such as iRig (I have one of those, too, but only as a back-up). iRiffPort plugs into the Input/Output interface on the iPad and this connection gives much higher quality.
The sound quality, through both headphones and plugged into a PA, is excellent and I have actually done a few small gigs using only guitar, iPad and my Bose L1Compact sound system.
I've never been a 'That Sound' purist, but I get great tones for the music I play. I also use an app called One Track Mind, which plays my BTs in single-play mode, straight out of my playlists - no having to keep remembering to hit the pause button when a track ends!
Now, my iPad is not likely to replace my main rig in the immediate future, but I definitely recommend using your iPad in this way. There are new apps coming along all the time and they are getting better and better in the way they allow you to create tones. Go for it!
