Spam Cube antispam appliance to hit soon

"This remarkable little tool costs only $150 and sits quietly next to your cable or DSL modem, requires only a few moments to set up and works with any email service out there. There are no license or subscription fees to stop spam, and one Spam Cube can protect up to four computers."

This is a very clever idea, however I have to say - why the heck didn't they just build a basic 4-port router into it? That would be useful for those who currently have their cable or DSL plugged in directly to their computer - and could therefore benefit from the firewall capabilities of a router. Anyway, a nifty idea, and it comes in SPAM pink too!
