There’s a lot going on here with the inside.
A full size divider allows clothes, shoes, or other items to fit the entire height and width of the backpack.
Additional pockets on the inside make separating documents and other thin items easy. But the abundance of pockets aren’t too useful besides for thinner items.
The memory foam padding allows a laptop and/or tablet to be stored away and be protected. If you travel often with your electronics, then this is a key feature. Just be sure to buy the backpack size that fits your laptop, whether it’s 13″, 15″, or 17″. If you are bringing along a large tablet (like 12″) and it has a rugged case on it, just double check that the 13″ backpack can actually fit it first, otherwise size up.
