Yea, I wouldn't go without. To much out there that can be easily missed no matter how careful you are. If you will be on the internet, better have something.
Personally, Id stick with NIS. Not only for its definition based scans, but SONAR to detect new or unknown therats before they get you. Plus Spyware and Anti-SPAM.
Its actually one of the lightest suites out there considering all it does. Ive been running it for years on several PCS and haven't had a infection yet, although some Warnings and Quarantines have popped up.
I too have tried MSE and couldn't really see a performance difference between it and NIS. Perhaps some setups would? Not sure.
But being you can get it for a discount at Amazon for 25-30$ or so per year, I found it was really worth it for the extra features.
Either way, if you do not like it try something different.
But please, do not go without anything if you will be connected to and surfing the net.
