I'm a bit confused by this poll's "in production" wording. I have a SSD in my laptop, but I read "in production" as "in use in the server room" (maybe that's just my background in web hosting coming out.)

I'll answer "in production" with the caveat that important data should never be stored on ANY single disk or in any single location. (You'd think that would be obvious, but unfortunately, it's not, or else hard drive recovery services wouldn't do such a great business.)

I'm quite happy with the SSD in my laptop. I don't get any better battery life, but it does make the laptop "feel" faster.
