All the cheap backpacks I owned either fell apart, or the straps wore out.
I am using two bags.
My main bag is a GoRuck GR1. It doesn’t have many internal pockets, but it used Molle straps and I have a few pouches strapped to the inside. The lack of pockets is a plus. I can usually throw a GMT-game-sized box into the main compartment. There is a laptop area that is very accessible. The bag is a complete tank.
I also have Tom Bihn Ristretto that they sadly retired. It has also held up fantastic for over 10 years.
The Osprey packs are great. I’ve got a few Raptors of different sizes. I have a Raptor 6, which it looks like they don’t make any more. But on that one, my chromebook just fits into the water reservoir pocket. I’m not sure how its width compares to the Katari.
I have an ebags Mother Lode travel backpack that I originally got for a weekend trip to NYC and it was fantastic. It has so many useful pockets and compartments. Ebags also has several laptop backpacks that look good as well.
I have only gently used my travel backpack (thanks, Covid!), so I cannot comment on durability, but it felt solid. I would go directly to the ebags website to check them out rather than wading through Amazon.
I carry a MacBook, 12.9 Ipad Pro and Remarkable tablet as standard with all the cables, power adapters, mouse and other gubbins. Two side pockets - for a water bottle and an umbrella.
I’ve been using it for around 18 months and it still looks like new. I’m very pleased with it.
