There's a lot missing from the description (and the developer's page, since that is all the info on the developers page).
1. How does this work? Does it require an internet connection (like all the other translators out there). If not, how are updates acquired, and how big of a footprint does this have.
2. WHAT LANGUAGES? and what translation vectors?
It would be really nice to know these things, as it would be great having a reasonably accurate translation program for a laptop.
On top of that the "fix for uni-" scares me, as all language translators except those that only use roman based systems, should have full unicode support from the very first coding.
Then you have to be forced to 10.5 to use it, and unless I get a dedicated 10.5 laptop, that just isn't going to happen. Apple killed too much compatability with the new system.
