I love Steam as an option, and as long as there will always be both traditional retail channels to sell boxed games it can really benefit everyone.
I too couldn't find my Half-Life box or CD if you put a gun to my head, but my Steam account is still installed and I can play HL/CS/DoD whenever I want on any comp I feel like installing it to. With a higher speed cable connection I didn't even bother burning a backup when I last reformated my comp. One thing I did learn was that you can never assume you remember your username for something that you load almost daily if it auto-logs in. But 30 seconds after filling out the lost username/pass form on Steams site I was reminded of the old email addy I used and I was good to go.
