are we not talking about gamers who choose to stay on XP and are upset at not being included in the new drivers?

I am saying 100% of gamers on XP should move to win7. You're saying that grandmas should be included in the 'gamers on XP' demographic. Grandma's do not need to upgrade (if we're not considering security consideration). Therefore, you're <100% of gamers on XP need to upgrade (diminishing the importance of upgrading by implying there are reasons not to upgrade). I am saying that grandmas should NOT be included in the demographic, therefore bringing the conclusion to: 100% of gamers on XP should move to win7.

EDIT:

but really, XP is highly susceptible to drive-bys compared to win7. that much is obvious (doesn't even microsoft even admit this?).
