Since nobody replied to my post about cold storage, and I've noticed there are several more people recommending blockchain.info despite the recent attacks, I'd just like to add that if you do use blockchain.info, it would behoove you to enable 2-factor authentication (SMS confirmation texts) and consider using the "disable TOR access" and "restrict IP address" options. It might also be wise to create a new wallet every so often, or to keep small amounts in separate wallets. And of course, if you are going to be using bitcoin, it is absolutely imperative that you use reputable antivirus and antimalware solutions. Your whole life you've been hearing about protecting yourself from hackers and viruses, well now it REALLY matters (not to imply that it didn't before, but you know what I mean). Take the necessary steps, protect yourself. You'll be glad you did later.
