Does anyone really notice a difference between SP2 & 3? I just got the info update to receive SP3, but before I get it, I want to know if there is really any big difference overall.
Go ahead and get SP3 - it has quite a few security patches, etc. You will not see a major difference in your day-to-day computer experience...most of the updates are "behind the scenes."
It's mainly security fixes. Which, are probably some of the most important updates you'll need on any windows system. Always install security updates for windows. =/
