What's the point, when you just have to convert it back to analog to do anything with it?
It has the D/A converter in the guitar, which means no loss of signal etc using analogue leads. If you consider that the majority of guitarists are using digital pedals (converting analogue to digital/ digital to analogue each pedal) you can imagine how that would create artifacts on the signal.
These days most home, pro studios and many live guitarists are using virtual guitar rigs (like [url=http://www.native-instruments.com/index.php?id=guitarrig3]Guitar Rig[/url], [url=http://www.ikmultimedia.com/Main.html?guitarbasssoftware/index.php]Amplitube[/url]) you could also use a re-amp (after recording) to experiment with real pedals/amps so it makes sense... Also, it looks great :-D
Not for everyone though...
