XP? Still less:
Secunia has issued a total of 178 Secunia advisories in 2003-2007 for Microsoft Windows XP
Red Hat 4's 266 known vulnerabilities seem to be in a league of their own LOL.
You're still somewhat on an apples to oranges comparison.
Besides, as I said earlier:
^^^^^^^^^Furthermore, to bring Windows to the same level that Red Hat is at, you also have to include IIS, MS Office, MSSQL, photoshop, and several other packages that isn't included with a default install of windows.
You have no argument.^^^^^^^^
This argument *can* be made into an apples to apples comparison. But you'd lose that one.
Besides, RHEL has 0% unpatched. XP doesn't. MS is proving it's insecure ways.
And despite having less unpatched vulnerabilities, Linux is still higher performance.
