I've had my old Baggalinni messenger bag for 11 years, and I won the rfid messenger bagg in the Holiday giveaway. I just used it on my Universal trip. Here are some thoughts.
Pros:
the contrasting interior is nice.
The dual front zip pockets hold earbuds and external battery nicely
The body can hold a kindle.
The size pockets hold your phone nicely, also a wand nicely.
The internal zip pocket akes a nice lipstick holder.

Big con:
I really missed a "waterbottle" holder. The zip side pockets wouldn't hold a reusable mug, Yeti cup, or a metal water bottle. I ried using a carabiner, but that was a PITA with Universal's lockers.

But overall I love the bag.
