You also need to open your Ledger wallet so in reality it is double the size when you use it.
The size when I'm using it is fairly irrelevant since I also have to have my laptop open to use it. It's the size when I'm trying to inconspicuously carry it around with me that concerns me.
And why would you ever carry your fortune with you all the time?
I don't. The majority of my holdings are on various encrypted airgapped wallets or paper wallets. However, I would rarely put more than $50 on a mobile wallet, so if I'm out and about or traveling and anticipate the need to use bitcoin, then I want a small hardware wallet I can easily carry with me.
Sorry for messing with your Ledger worship gang, but somebody has to.
I am very much not a part of a Ledger worship gang. I like their devices, I hate their software interface, and now have major concerns regarding their attitudes towards customer privacy.
I never carry it with myself or on my keys
As I said above, that's entirely up to you and so you may love the Passport. As someone who
does carry a hardware wallet around, this device does not fulfill the criteria I need it to. Each to their own.
