I recently bought a Samsonite slim business backpack for around 200€ (wIth a discount in the christmas sales), especially designed for the 16”, and it’s great. It’s well designed so it does not look big when worn and has a special pouch that protects the laptop. It supports the weight well, especially considering that I also carry around a 12.9” iPad.
They also stock carry bags, although I’m not sure if they make one specifically for the 16”. I’d go to their shop and see, rather than risking ordering online and not liking the design/shape.
How does the size of the 16" compare to the 15"? Didn’t the screen get bigger because they removed the bezels/borders and not by increasing the overall size? So, it’ still (bag-wise) a “15”)?
I just went through this dance myself after upgrading laptops. I ended up just ordering a half dozen or so bags off Amazon and tried them out. The free returns on them all helped make it a not costly proposition.
While the 16" is slightly larger than the 15" retina, it is smaller than the pre-retina 15" models. So depending on how old your existing bag is it could go from an easy fit to just fit (if the 15" retina was cozy) or no fit. Check out anything you might buy first!
