I use both Mac's and PC's both modern OS's are safe
I think as with many Apple fans they always compare Windows to Mac's in a filtered comparison. Always using XP as a example rather then Windows 7. I have used both Windows 7 and OS X Snow Leopard and now Lion. Never had any trouble with any of them with Malware or Viruses. But its never been about OS X being safer or better. Its about users. Mac's still only make up about 12% of computers. Do we really think any hacker will want to try to attack not only a good OS but one that is only used by 12% of computer users?
