Query: works for me!

I do some pretty arcane dictation with lots of technical vocabulary, and have found the system up to my demands. I have worked at training the system, and it keeps on improving. I do find some of the interfaces a bit awkward to work with compared to the system I use with my PC (Naturally Speaking Standard Edition), but then, I've worked with that system somewhat longer. If the recognition of iListen improves with use as well as Naturally Speaking has, I will change my rating to 5 stars.
