I registered for and received a JJ Cole Mode Bag, and did use and like it during my maternity leave. By the end of maternity leave, I'd had enough of that bag. It was too deep and not wide enough, I was always digging and having to pull everything out to find something. Additionally, as he started getting older and I had to bring more things, I didn't find the pockets to be incredibly convenient. We switched to the Diaper Dude Messenger bag that I bought my husband when DS was 3 months and have been using it exclusively ever since. It's not very girly or feminine, but I learned very quickly that practicality won out over good looks :)
I do think a lot depends on whether you are going to be going back to work or staying at home too. I work FT, so I only use our diaper bag on weekends and if we are out to dinner or something during the week. If I was carrying it around every day I might want something a bit more girly. Just my two cents. Good luck in your choice....sometimes it takes a while to figure out what you really need, after your little one gets here!
