Hardware wallets(Ledger Nano S) need connecting to PC, the PC is online.

The private keys still doesn't leave the Ledger device; regardless if it's online or not. My point still stands.

"Your private keys are held in a Secure chip, and they never leave it. Whenever a transaction is signed within the Secure chip, the private keys never become visible to the computer the Ledger device is connected to. A compromised computer will never be able to access the contents of the Secure chip."

While, I think the bigest problom of hardware wallets is seed-words backup issue. Keys loss is big threat than theft for most of users

This "issue" you're referring to is an "issue" of all wallets that's using 12-24 word seed backups, not just hardware wallets.

1. Without airgap, no one can confirm "keys will not leave device". iPhones/iTouch also have the keychain(Secure Element/chip) and application sandbox mechanism, which can also be said: if the iPhone did not break jail and the wallet app did not disclose your keys then no one can touch your private-key on the device(iPhone).

2. Multisig and redeemable address can solve backup "issue". One key is encrypted backed up will never lose, other cold keys with airgap protection.

3. I still think most people will forget and lose their bitcoins themselves. So for users who are not familiar with tech and neglect data backup, using a soft wallet even a web wallet is not a completely wrong choice.
