I keep reading these wonderful reviews on Distrowatch about new Linux live cd/dvd's. Then I download them, burn the iso's and try them out. Invariably they turn out to be crap. If they work at all they're slow as can be, some of the apps hang or crash the system, you can't acces the hdd's, the desktops are flaky, etc. and so on.

The only live cd/dvd's that work are the various flavors of knoppix.
