I have the Pimsleur Hebrew I in my car. I only started listening this week, though. I got through lesson one, though it took me about three listenings to get it all down (I can say "I understand a little Hebrew" and a couple other basic phrases).
I don't know that I really have a use for Hebrew - but it would be fun to learn. I know a smattering of German, Russian, and Latin, but none of them very much in-depth. Studying Russian kind of works against me - I keep wanting to slant the Hebrew vowels.
I haven't looked at written Hebrew. I have "Aleph Isn't Tough" book one, but I haven't cracked the cover.
For me, Hebrew is one of those things that would be cool to do but never rises high enough in the priority list to actually work on it...
