Having biometric support is a little bit too much and unnecessary in my opinion. It's pretty much just a little bit of convenience in exchange for less security, which isn't really worth it in my book. Bluetooth as well; though someone doing a man-in-the-middle attack on you while using your bluetooth hardware wallet is quite unlikely, it just adds an additional attack vector. The Ledger Nano S and the Trezor One is still the best in my opinion.
Pretty much this.
It's become an old adage in security circles that biometric data should only be used for identification but never for authentication. There's simply too much downside on using biometric data for the latter (e.g. biometric data is easier to spoof than most people are aware of, it can't be revoked and exchanged for new credentials). Accordingly I have my doubts about the security awareness of any hardware wallet vendor following this approach.
