I love my XDJ R1 to bits, but it has issues. Main annoyance is that you must export drives differently for the R1 (where as the XDJ Aero can interchange with CDJ drives). Certain USB drives do appear to be able to crash the R1, but for the most part it is pretty stable. There are other issues such as the lack of single play mode (only continuous, which if you want to scratch your records in gets in the way as you're constantly scratching back into the last track). I too am awaiting the next model on the XDJ lineup, as I'm hoping it finally completes the feature set we're all looking for.
