Cause you spend all your money on graphics cards ?
Because I don't like being locked into an ecosystem which ultimately breeds inferior overpriced products.
I won't use crapple products either for the same reason.
@LambChop you could do yourself and NVidia a favour and buy an AMD card when the next gen of cards arrives. The alternative is to be locked into an ecosystem with little competition paying ridiculous prices for second rate products in a couple of years time.
If people really want to save NVidia (from themselves) and their wallets from taking a bashing, when the next gen arrives buy an AMD card.
