Before you answer this please consider that there are many antivirus packages, firewalls, rootkillers...blah, blah, etc, etc...... to handle any threats that may arise. If this is the case then why do we update, to improve the perfomance (yeah right).
I just finnished a fresh re-install after a crash (the crash was caused trying to install Ubuntu) and didn't update, my system works better than it ever has including my ultra sensitve "Microsoft Mouse" a wireless notebook laser mouse 6000, it now lets a screen saver start without unpluging it (and no it wasn't the mouse settings).
Anyway i'm really interested in everyone elses point of veiw.:confused:
