Thanks for the report.
I made my first trip on the A380 last week LAX-LHR. I thought the F product was definitely a step up from NF on the 747 and even the 777. I particularly liked the storage compartment near the arm rest which is something lacking on the other aircraft. There is more space overall and indeed privacy is better although I think adding a small door to close the suite would have been a good idea. All that coupled with a better amenity kit in a useful bag at last, and the special menu all make for a great experience (although admittedly I only had breakfast as it was the later flight out of LAX).
