I'm surprised their revenues have gone up, though I imagine it's more to do with exchange rates than demand for their software.
Who in their right mind uses Symantec products? You constantly have to re-active the AV to download definitions, their firewall is shit, and I resent my boot time going up by 3-5 minutes the moment I install their AV suite.
All they seem good at anymore is destroying the [decent] products of companies that they assimilate.
