I find it pretty appealing that I don't have to secure my own wallet, as this is a non-trivial manner (and I'm not even a complete security noob). Sometimes its easier to trust a 3rd party (that has a working history) than worry about it yourself. Also I think its kind of ridiculous to expect them respond to emails claiming "forgot my password", if they haven't registered an email with the site. The option of having no reset option is also nice as it removes a huge potential for unauthorized account access.
It took me a while to jump on board, even after reading the whitepaper and thinking the same thing. Nice job articulating the difference between those who do and those who wait and see.
