I've been shopping around for a new laptop bag for almost a year now. I had some very specific things I was looking for and this bag exceeded all those needs and my expectation. I was willing to pay way more than this bag cost.I wanted a smaller bag w/o an overnight compartment. Let's face it, I'm a girl, the overnight compartment in most rolling laptop bags is not big enough so I had no use for it space. Also my company just switched to Kindles for all of our materials, so I don't carry around training manuals anymore. The space inside the bag is nice, I can put in my cord and wireless mouse and still have room for 2 medium size binders and there's a compartment in the front that will fit a file folder, so even though it's a small bag, it has good amount of room inside. When I have the bag hooked onto the rolling system, I slide my power cord and wireless mouse into the space between (where the raincoat is at) so I can have more room into the bag for travel things (snacks, bottle water - yeah, I know it's stupid by the laptop), this allows me to not have to carry a purse.The other thing I wanted was a detachable from rolling bag to shoulder bag. I use the rolling bag to get around the airport and a shoulder bag when I go to visit clients. It's just easier to get in and out of doors w/ a shoulder bag. I also wanted a bag that I could slide onto the handle of my luggage so I only have to pull around one bag. The bag has small details, like the zippers used to hook onto the rolling system tuck in and hide, so the bag looks sleek and polished when used as a shoulder bag. The raincoat, which I thought I'd never use came in handy when I went to Seattle.It also has a very girly style and color. I got the orange and the color is super bright and beautiful, has a pearl like finish and cream trim. For those not into super bright a co-worker got red and that one is a deep red (no pearl finish), so it's not as bright, but still beautiful.It will fit under a seat in an airplane, if you HAVE to. You'll need to slide it in on its side and about 2 inches of the bag stick out, so it really cuts into your foot space, so only do it if you really need to. On my first trip with my new bag the flight ran out of overhead space and they wanted to check my bag (no way...that will ruin the leather, plus I had my laptop inside are they crazy) so I got it under my seat and I had the window seat
