Why would you go with a 10 year old operating system that MS would like to drop support on?

Win7 works fine, has been solid for me, and MS will be very diligent about patching it for security as needed. Install the MS Security Essentials and you should be good to go unless you are really, really foolish in your web surfing/spam email opening habits.

MS Security Essentials isn't very effective against MBR Rootkits.
But Windows XP is vulnerable to MBR Rootkits, hence the question about Windows 7.
But the question "Why would you go with a 10 year old operating system that MS would like to drop support on?" is partially answered in post #24,
and that is total cost for the switch to IMac.
