@btchip I have a couple of Nano S on back order and look forward to writing up a hands on review as soon as I receive. I am very comfortable with my Trezors but really need a hardware wallet for Ether, and using more than one brand of hardware wallet never hurts. At $66 buying a Nano S is a no brainer.
I am a big fan of passphrases. I like using a PIN and a passphrase protected seed but realize the secure element used by Ledger is more resistant to brute force attacks, so a passphrase is not essential though the option would be welcome.
Why did Ledger decide to limit PIN to four digits? I bet many users will use the same PIN as one of their credit cards. Increasing the PIN to five digits would be so much more secure. I hate the idea of a thief getting even a one in a thousand chance to guess the PIN.
