You seem to be forgetting the golden rule of "use cases"... which, as I was quite fond of telling my ex, is "Everyone is NOT you!" 
Simply because you don't see a need for X or you don't want to do Y with your device... doesn't mean nobody else does. I've travelled (internationally) with my ledger before... a small USB key like device barely gets a 2nd look from customs officials when you're travelling with a laptop and have 2 other similar looking USB keys in your bagetc... and having access to "emergency funds" when away from home for 3-4 weeks is useful... especially when your missus likes to shop up a storm! 
And I'm not sure why you seem to think that everyone here "worships" the Ledger... I like it, but as someone else mentioned, it's far from perfect... but then, so is my Trezor... and Electrum... and Mycelium... and Bitcoin Core for that matter... but I still use all of them and would be happy to recommend any of them depending on the use case.
