In Norway, we have BankID as well (works well on mac/chrome, though), but we also have a choice to use non-java MinID ("MyID") for logging in to do taxes/healthcare/education/etc. Signing electronically is still only BankID and java, as far as I know.

From a convenience-viewpoint, I think it works quite well, but I don't know how secure it is if an adversary is determined enough. It's basically (birth number) + (personal password) + (either a key sent to your phone or a randomly chosen PIN from a paper you've been sent through regular mail)
