So this is a case option, (not a bag) but it is much slimmer and lighter than the uber-sized NI one.
Width: 14cm vs 21cm for the NI Case
Weight: Under 2kgs vs 8.7kg for the NI Case
Make: WAG Heavy 4040 - Made in germany
Cost: Case + foam inserts around the same price as the NI Case
It will fit the S4 and a 13" mac laptop as well.
The foam padding protects the S4, holds it in place, but does not press on any buttons or connectors like the headphone vol control etc
Having the S4 on top of the closed case works well for extra height if you are on a lower table.
Also, some pads under the S4 allow me to place a 13" mac laptop under the S4 (like the new Pioneer controllers do) - see photo below.
