Err, no - we never used 3.5" drives. Even my mp3mobile, which I built for my pleasure only used a 2.5" drive.

I doubt SB would be interested in a company with a tenuous grip on hardware (ie: stick a whole PC in the car, 3.5" drives & all) and as yet totally unproven software. Obviously, I can't speak for them, but it doesn't look anything like a product yet...
