The output can be analysed in many software packages away from Sawtooth. Sawtooth controls th data capture beautifully.
SPSS can provide data mining capabilities (there are others like SAS).
Excel is okay for charting, summaries and pivot tables, etc.
There are cross tablulation packages like Surveycraft, Quantum, etc. (and there's many more).
This all depends on what you are trying to achieve?
