I am inclined to agree. For most, the process of downloading a wallet, installing it, allowing the blockchain to download and take up 20+GB of space, then trying to figure out how to secure it, and acquire Bitcoin, is daunting and intimidating to them.

However there does seem to be an influx of services and even technology built on top[ of the blockchain, that is aimed towards the 'average joe' and adapting to their needs. Things like Bitpay take a lot of the hurt out of the process for non-technical minded folks, and wallets like blockchain.info and even electrum also absorb some of the brunt.

Maybe over time the core Bitcoin wallet will evolve into a much more user friendly experience, and maybe more technologies will be created to make buying, selling, using and trading bitcoin as simple as a few clicks and easy enough for my grandmother to use (she is so technically-declined that she used to think that her dial-up internet would interfere with her tv shows, so she would never let anyone in the same room as the computer when her show was on).

Blockchain.info has a problem. New people hear 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.
