Paging the Hive Mind: speech recognition software

[muninnhuginn]

Okey doke. So I've got the new PC and laptop. One of the things I was going to try out--from curiosity, because it might be useful--was speech recognition software and dictating to my machine (Looby Loo, too). So there's Dragon NaturallySpeaking and IBM's ViaVoice that I know of. Are there others? What's good? What's not?

What I want to be able to do is to dictate into a word processor/text editor other than MS Word. Or FrameMaker directly, since that's where most of my words go. Interaction with a browser--Opera/Firefox--would be good as I'm using both Writerly and Google Spreadsheets fairly regularly and expect to use the latter much more frequently. So the requirements aren't huge and complex, but my choice of software is non-standard (or is that simply, non-Gatesian?).
