The gigabit port and adapter are for your server, the 8 10/100 ports are for your workstations. Nice setup for home or small office. For $105, you can't beat it. Most places sell for around $175 or more. As with many hot deals, its not so hot if you don't need it. But, if you've got a server, and I know some of you do, this is a nice price/performance upgrade.
BTW, this is my first hot deal, so, please be gentle.
