I feel that turbo mode should be disabled because I just downloaded opera and enabled it thinking it was going to make my browser faster when it actually slowed it, I was loading websites side by side seeing if it was faster than chrome and Opera was slower so I almost uninstalled it, then read that turbo mode is only for slow connections.
A noob would have just uninstalled it thinking Opera was junk, maybe rename Turbo mode to Turbo mode (for slow connections).
