The only thing I still have some confidence in are air-gapped wallets, but even there things are clearly not completely secure considering what happened.
Nothing has changed. Airgapped solutions are great and they work. Airgapped and stateless systems are even better. The problem was in the implementation, resulting in not enough randomness during seed creation.
Most hardware wallets make entering a strong passphrase cumbersome. Even if the thing has a decent keyboard (which none do, not even LOL'DCARD), do you really want to type a long passphrase every time you use it?
I am doing that. My Jade is probably the most cumbersome one, but I am still using long and complex passphrases with it. It takes me several minutes to enter. But as I said earlier, I am fine with giving up convenience for an increase in security. Besides, it's not like I am using it daily. One part of my holdings are on that Jade but I haven't accessed the wallet for over a year. I have a watch-only wallet on a different machine I can access if I need t see my balance.
