Flash takes a lot of CPU on 32-bit also, on my system about 50%.
Fortunately Youtube isn't running all the time. And you can go back
from unstable to testing by using apt pinning (
http://jaqque.sbih.org/kplug/apt-pinning.html ) you give the "testing"
repository a preference number of over 1100 and apt will downgrade
your system. I'm the kind of guy who keeps on screwing and tinkering
with his system, forcing upgrades and removes, so I've had hundreds of
serious crashes, most of which resulted in reinstalls. Since I started
using Debian, the reinstall rate has dropped radically. Even though I
broke my package system on several occasions, I could always fix it
somehow, so compared to RPM-based distros, I personally find it more
user-friendly, or user-error-friendly.
