Here's a shameless plug for the software product I work on. Although it has some custom features for geochemical data, it's flexible enough to be useful for generic datasets. You can get a trial version from: http://www.ioglobal.net/ioGas.aspx

"Through the ioGAS dynamic graphical environment, you can interact with the data in real time, making it effortless for you to detect patterns, anomalies, and relationships across your data. Combined with optimised workflows, you can produce high-quality interpretive outputs with the confidence that you have applied best practices developed by a team of geochemical experts. Most importantly these results can be produced in a fraction of the time taken by traditional tools."

Are you sure this isn't Apple screaming "mine, mine!"? Case in point, I bought a new VW a few months ago and the only way I could get something resembling a factory aux-in was to get the stock iPod adaptor (which the dealer threw in for me). I didn't have an iPod so I had to go and buy one so Apple got a new customer, albeit a reluctant one. To make matters worse, the factory adaptor's navigation is pretty crappy (granted, not Apple's fault) and I'd be much happier if I could use my Zen player and continue to use it's controls which are much easier to use without taking my eyes off the road. But I can't because now I'm locked into the Apple universe.
