Dont know much about netbooks but may be you should go for less is better because of performance? I know Nortons Internet suite run sweet and 360 just seems to be an extended version. Install trial version of 360 and test - first uninstall what you use now. How flexible is it? Can you disable features and so on.
Have you seen feature list of 360? From what I can see only 1 thing speaks for a suite and that is firewall. Will be easy to handle and 100% compatible with everything else since all is Norton. I actually like this free firewall a lot
http://www.tallemu.com/free-fi...otection-software.html but you cant expect much plug and play with free 3rd party firewall. There is a reason Norton brags about theirs being "quiet". Noisy means work and questions for you - or is it higher security level?

I dont see much need for "better" firewall at all but like the one I mentioned. Satisfy control freak with little effort required and helped by easy to handle interface. But if you pay up 3rd party firewalls often become monsters, half an AV too

dont rush purchase of super firewall without checking it out.
40$ should not kill you but think of netbook first. Last night I saw a dude saying Windows 7 ran great on his Acer netbook, 299$, 1.6 Atom cpu I think. So I dont know if a suite is a worry or not. But you wont be racing around on torrent sites or experimenting with keygens right? You also have some knowledge about how to navigate internet? This is for school I guess. So where is the need for 360, anything else than a little AV for unknown usb things could be considered fluff. Could turn off autoruns/play and settle for Clamwin on demand

Then again may be not - but think about where risk comes from, your own level of experience and know-how - focus on potential risks, dont try to prepare for a war you are not part of.
I would probably get the new free, or rather already paid for, Microsoft Security Essentials
http://www.microsoft.com/security_essentials/ Is in beta but seems stable, no major issues I think. Just waiting for Windows 7 to get out. They could work a bit on lowering memory usage a bit... but runs just like Nortons stuff, max ease of use so you can increase productivity as they say. Dont complicate computer or your life with silly concerns like I must use my Norton Account to fill out this form or Im in danger. I know it is sillly but I dont feel safe!!! Then you have lost the game about your money

Also unless you compare the worst with the best among these security products there is really not a huge difference in how "safe" you are.
