Well if I had life savings I WOULD have invested a lot into it right now, but as it stands I am trying to use my BTC wallet as my bank. Keep all of my money in BTC and either use BTC to buy my stuff or transfer it to my bank account and withdraw is instantly.
If you are keeping ALL your money in BTC, I hope you are spreading it out amongst several wallets. You don't want all your money to be gone if something bad were to happen...
It's harder to secure several wallets than one. It's better to encrypt your single wallet to prevent anyone from using it if he gets his hands on it, and than backup it in several places, including the cloud. My preferred backup is to email it to myself. Google will keep it safe forever, and it's easy to periodically email it again if you exceed the limit of unused keys, which will force the wallet to generate the new keys.
