I actually bought this as an alternative to my regular messenger bag, which is too big to bring along on shopping trips and city sightseeing trips . There's space enough for my Kindle, digital camera, and clutch wallet, plus maps, mail, and a 9 x 11 envelope or legal pad. My main kvetch with this bag is that there's no exterior pocket to hold a cellphone, keys or a bus or subway pass. There is a D ring if you want to clip your keys onto that, but I keep my house and car keys all on the same ring and don't want them attached to the bag. I wondered if whoever designed this bag was a guy who's used to keeping things in his pocket: I don't know of many women who do, especially since most women's clothing lack serious pockets. I would have been happy to pay a little extra to have a zippered pocket sewn on the back exterior of my bag: instead, I'll have to figure out a way to safely store those things I need to grab quickly while on the street.
The iPad messenger is the perfect size: just enough depth to accomodate a sweater or other bulky item, while the dedicated iPad pocket ensures quick access. Only one thing would make it better: an open pocked on the back.
I really like my pretty tweed pink bag, which I use as a purse as well as an iPad carrier. It is plenty big for my glasses case, wallet, a notebook, my transit pass, keys, phone and iPad. It is lightweight which is a big deal because the iPad is heavy enough already. I like the easy slip strap adjustment.
I was in too big a hurry when ordering to notice that I would need to order some pocketses for the bag separately. I really like pockets. If you haven't already I might suggest you offer a "buy the $15 pocket insert" option before checkout to anyone buying this bag. But that's my only suggestion for improvement. I like that the pocket comes with a zipper, especially for some of the more sacred purse items....
I wish the width of the bottom of the bag was just a little bit wider so that a standard manilla folder fits easily and nicely into it. the bottom ends up being just a little too small.
Love everything else about it though! Great work!
