I use this product along with the prototypical tablet sleeve/cover/stand that my Galaxy Tab 10.1 permanently resides in. I use this to keep accessories with the device when travelling, not for daily protection. The tablet slot is perfect and the divider within this attaché has a small velcro strap to keep the tablet in the case. That being said, the fit for my device is so good that the tablet is never in danger of just falling out anyway. Occasionally the divider will get under the tablet when putting it in this case, but simply tugging on the divider gently pulls it out and you can get on with your life - it's a triviality, but a drawback nonetheless.
The divider is also decently solid and rigid so accessories placed within the case in the other side will not press on the tablet and damage the screen or falsely activate it. The space for accessories was admittedly smaller than I had envisioned, but that was just my spacial guess prior to receiving it. The attaché is exactly the size it claims to be. I only mention it should others be expecting larger storage capacity as I was. It fits a charging cable, stylus and flat DC adapter well, but the DC adapter pushes it as far as I would be comfortable as far as item size.
There is a shoulder strap included that I didn't see mentioned and was assumed to be there anyway and I was pleased to see it was. It is adjustable to be comfortable for my 6'1" height. I would highly recommend this to anyone looking for a slim case allowing for accessories.
