In other words, exactly like the first Bitcoin wallet ever created (Satoshi's), but less secure (subject to the JavaScript being MITM'd, something breaking out of its JS sandbox and getting your private keys, keys being recovered from de-allocated memory because they can't be wiped by JS, etc.)

I'm just not a big fan of blockchain.info, so I have a strong reaction to midas's gushing above. What does blockchain.info do that "wasn't possible before"? It can't take credit for Bitcoin itself. It's like an online bank? Doesn't seem very innovative in that sense.

Again, the things that might seem like pluses (being able to access your bitcoins from any computer with an internet connection and a browser; keeping your own keys) are also really dangerous. I'd rather just use an actual application that lets me keep my own keys, without being subject to the browser's attack surface.
