Re: Such an enigma...
I'll use Internet banking when I can buy a 64 gigaqubit quantum computer and there's a way to encrypt the communications, storage and credentials that's been mathematically proved uncrackable
FTFY. Unless your bank is already using some kind of mythic "uncrackable" security, your account can still be pwned by many other methods: attacks on the bank's systems, ATM skimmers, spear-phishing bank execs and sysadmins, social engineering the call center, finding one of your checks in a dumpster after it was scanned by whoever you sent it to, etc.
Internet banking is an attack vector, but it's far from the only one.
