While not the first competitor to the ASUS Eee PC, the ECS G20IL (umm…) looks pretty sexy and offers some impressive specs.  The price is set to be sub-$500 and will offer three USB ports, WiFi, HSDPA, webcam and more.  No info yet on the other hardware specs.  Check out Engadget for more info.

Perhaps the ECS G10IL could use some help in the naming department, but it certainly isn’t having any trouble bringing a bit of class to the subnotebook market.
