I added some pockets, including an exposed zippered pocket. Now I can slide my laptop in that along with the cord. My mouse fits comfortably in another pocket.
Everything is all tucked in safe and sound. I fused some fusible fleece to the lining, so it's padded.
I thought about different handles and straps and decided on two 27" handles - that I padded with fusible fleece. These seem to support the weight of the computer better than anything else.
I love this bag. It's big enough for my laptop and any other goodies I may want to carry.
