Oh I see. Newegg isn't promoting it with USB3 ports, but just with 3 USB ports. Well the Asus newsletter I just got makes it very clear. As the newsletter states that the Asus N61Jq is one of the first notebooks using USB3, up to 10 times faster than USB2.

You can buy adapter boards with USB 3.0 (for $30) if you have PCIe. bob

I might have to look for an expresscard version for my laptop. Perhaps when prices drop a bit and I have USB3 peripherals, LOL. I've recently invested in USB2 fan-cooled 'docks' so I can access the couple of 1.5TB HDDs I bought when I was still using a desktop from my laptop. I guess they'll be redundant soon. Oh well, they're fast enough for my current needs (backup and storage). -- Shaun. "Give a man a fire and he's warm for the day. But set fire to him and he's warm for the rest of his life."
