When I had bought my gateway laptop, I had bought this backpack with the computer. I have had used a shoulder type of bags, but didn't like them so well. This fit my laptop perfectly at the time. I did not have a big screen at the time so it worked for me.
What I had found about this bag is that it did have plenty of room to put my computer and accessories in it. There was a spot for the laptop. There was a spot for my cooling fan. There was a spot for my mouse and external mouse and hard drive. I was able to carry everything that I needed to carry in it.
I had found that I had room for some room for books and folders as long as it was one class as I did bring this with me at time to class when I was away at college. I had the computer for 4 years and the bag is still in great shape like the day I bought it. It shows no sign of wear and tear and brought it back and forth between school and the train to home. The only thing is, is that it has managed to get dusty over the years, but no sign of wear and tear like you would expect from a bag carrying a lot of things I think I had even carried my pens and purse at times.
