That Seashell 1015 has the white plastic shell that ASUS' Eee line-up has become famous for, though the 14-hour battery life is a definite improvement over the 3 hours the original Eee had. The battery is removable too—another bonus.
The 1016P is for "mobile professionals," and has a brushed aluminum casing with "long-lasting battery"—though ASUS doesn't specify just how long.
My pick of the bunch is the 1018P, which is the thinnest Eee PC ASUS has ever produced, at 18mm thick. It has USB 3.0 ports, a fingerprint reader, and 10.1-inch LED-backlit screen. The tiled keyboard is almost full-sized, and it comes in four different colors. Pricing, availability, and other worthy tidbits of information haven't been proffered just yet. [TechInStyle]
