I am never going to maintain my own wallet
You shouldn't say never. Initiatives like bitcoincard, Ellet, and other attempts of air-gapped, dedicated-devices for managing bitcoins are popping up. Such devices would allow people to safely store their main wallet, even people which are not tech-savvy.
, and do all that stuff by hand, and every exchange has been hacked... not sure whats left to do?
If you really don't trust your skills in protecting your money, maybe you should try diversification? Have multiple online wallets, instead of only one.
But IMHO you should take a look at stuff like Armory and its offline wallets. It's not that complicated.
