First the Good...
Never having to worry about forgetting certs at home. Not having to rely on APs extremely slow mailing process to get certs and then hope that Canada Post doesn't lose our beloved package! I've had to forgo available upgrades because of this slow mailing process...thankfully only once!!
Now for the Bad...
I'm not so sure that I prefer electronic certs as I've been the recipient of a few "free" upgrades due to inattentiveness of some GAs

With electronic certs this will not happen
