Okay, look. I know you love XP, and you're not, as they say, the smartest person in the world.
But XP is NOT more safe because it's been out there longer.
Windows 7 takes all of that safety and then on top of that, is a new OS, which means that like Mac OS, there are less viruses out for it.
And who cares about safety anyway?
If you re-install Windows every 6 months viruses are no longer relevant to you.
There were Dos, windows 95, 98, 2000, ME, XP, Vista
Windows 7 is kind of a totally new project, having unlimited bugs is expected, except you tell me windows 7 is just a copycat of xp.
