I don't think it's that difficult. If people can online bank then they should be able to use blockchain.info.
What makes you think these things wont come? I'm sure there will be all sorts of wallet apps to do things like contactless payments and have advanced security features (finger print scanning etc).
Blockchain.info has a problem. New people here of the blockchain and they think Blockchain.info is THE site to go to. (Doesn't help how much it was featured on CNN's Inside Man episode).
Blockchain.info was hacked. It's not that safe, but if Bitcoin became mainstream tomorrow, Blockchain.info would have a TON of new wallets created. Think of that, while reading this: http://www.reddit.com/r/Bitcoin/comments/2ohnb8/how_i_lost_15_btc_on_blockchaininfo_without_my/
Blockchain.info will look like it's the best online wallet for a newcomer, but it has many problems, and should not be suggested to those new to Bitcoin to put all of their money into it.
The best online wallet is greenAddress (multisig + 2FA). However you know it doesn't exist the 100% of security, but I agree with you because blockchain.info isn't secure and the proves exist ( a lot of hacks related to the site, the famous RNG value).
