I never float wood floors so YMMV. The golden rule is to always follow the manufacturer's install guidelines else risk no love from them later if the product fails. Look for a bamboo manufacturer that's ok with their product being tongue/grove glued.

I prefer wood glued to floor - especially with concrete slab. I hate the hollow sound of a floating floor and even with a "superior" underlayment they still feel cheap. I'm close to pulling the trigger on Bamboo for the kids bedrooms. The stuff I've been looking at is very thick, 5/8", the kids bedrooms are upstairs and thus I could nail down but I'm more comfortable with glue.
