I had one of those as a kid. Took more pictures on that thing than I've taken on any camera since. I believe I was so excited about that camera that I even slept with it beside me a few times.
I also had one of those Kodak Disc cameras but they would quit working in a very short amount of time.
Also, currently still have a Sony CD 300 Mavica but in the 7 years I have owned it, I have barely used the thing. Probably because it's rechargeable and I'm too lazy to recharge the thing. I've used my iPhones camera more than the Mavica because the iPhone is always charged.
