Of course you cannot have a premium product without a premium price. The Seashell will retail for about $429.
Specs should be an Atom N280 (1.66GHz) 1GB DDR2 800 RAM, 160GB HDD, 10.1-inch screen (1024x600) WiFi (b/g/n) Bluetooth 2.1+EDR and a couple of USB ports. Battery life is looking to be around 6 hours, not too bad for what you are getting.

That gets you Intel's Atom N280 processor running at 1.66GHz, 1GB of RAM and a 160GB hard-drive, together with a 10.1-inch 1024 x 600 LED-backlit display. Connectivity includes WiFi b/g/n, Bluetooth 2.1+EDR and two USB 2.0 ports; there's also an ethernet port hidden behind a trick swivel-down cover. Since there's no room for a standard VGA port, ASUS fit a mini-VGA port instead; however, there's also a pull-out adapter hidden in the 1008HA's underbelly.
Other connections include audio in/out, a two-in-one card reader and the power socket to charge the integrated battery which, ASUS claim, is good for up to 6hrs runtime. You also get a 1.3-megapixel camera, microphone, and Windows XP Home.
