I flew SFO-SYD in 16A (first time ever in C!). Great seat in my opinion. I have an old rollaboard that fits perfectly in the metal bin airlines have at the check in counters. It fit SNUG in the bin at the window. That was great since I had all my stuff right there and I didnt have to get up out of the seat except to stretch my legs and goto the bathroom. You need to climb over 16B but it wasn't too hard. I could imagine its harder without the extra 5".

On the way back, sat in E+. I noticed the middle E+ section has ~2" more pitch than the window E+ sections. I measured on the floor inbetween the seat structure. This was on an old config.

One other thing. I noticed seatguru says that E still has projector screens even on the new reconfig 747??? Are they serious? I thought UA would finally get rid of those crappy things and put the seatback LCDs in like the 777s have.
