For us ordinary people: Is there any reason to use mult-sig (3xxx...) wallets?

[Eqvant]

Multisig gives us very high security. The security is important. I use Copay wallet from Bitpay. The wallet has a user-friendly interface. Try it.

More security.  If you had to sign transaction from key on your computer, then sign it from key on your phone attacker would need to compromise both devices.  Something like 2 factor authentication

For regular people I think multi-sig has no real advantage, Unless for some reason you want to lock your coins, Other than that multisig has no serious use and merely just some extra bitcoin knowledge.

I have been unable to think of any good reason why a single user would need or even want a 3xxxxx... wallet.

Kraken do.

Seems really logic in enterprise strategy of security ... you can't speend without muti-sig for valid spending.

no problem here.
only feature.

I do not see any real reason to use multi sig wallets. Especially for ordinary people.  And BTC confirmation times can be for hours, so better choice is to use simple online wallet, like Blockchain.
