Correct. Most people probably won't use 10Gb connections though. Save some cash and get something more appropriate for your actual needs.

True, that's why I threw in the bit about 10G ISPs or a 10G NAS.

If you already have the equipment that would benefit from this, $600 (after coupon) is a steal.
