As a proper Apple-follower I prefer not to support Bill, but the netbooks I'm preferring have *spit* windows 7 *cough* installed. So I was wondering whether it is possible for a non-geek to "overwrite" Windows with Linux. That's question 1 to you.
Question 2 is: What anti-virus-software shall I install? As far as google, openoffice.org and opensource.org tell me, there is no open-source protection software available.
Any suggestion is appreciated, as long as it doesn't tell me to get an iphone instead. See above.
Cheers!
