we absolutely need desktopwallets aswell since myself for example don't trust anything that i do not have under my own control. I think others may think the same way. What's not on your own system (desktop wallet) is not really yours.
I wouldn't use any onlinesolution for storing coins. I think it's not safe. An onlinepage with login and password is like an invitation for hackers to brute force.
i am actually pretty excited about nem. Can't wait for release.
i use a 512bit passphrase.. your saying that isnt safe?
i don't even know what that is
i got used to securing desktopwallets though and improved constantly on security and would be nice if i could use that knowledge for nem also.
I never lost a coin that was on my own system. But i lost quite some coins on hacked exchanges. I like my coins offline for that reason
edit:
the logic is: if it is online theoretically the whole world can try to steal it. If it is not online nobody has really a way to access.
