Just as a system featuring an Atom CPU but in a chassis with a 21in screen is eminently not a netbook, so too can the same thing be said about a 10in Atom-powered sub-notebook with a DVD drive. Nonetheless, that's exactly what the Asus Eee PC 1004DN has. The implication being that Asus' Eee design team methodology is pretty much akin to throwing spaghetti at the wall and seeing what sticks.
Disc drive aside, the specs of the 1004DN are fairly unspectacular. An ExpressCard slot and the use of a 1.8in - rather than 2.5in as is standard - 120GB hard drive mark the only other notable differences between the 10004DN and just about every other netbook on the market.
A 10in screen, 1,024 x 600 pixel resolution screen coupled with a 1.66GHz Intel Atom N280 CPU are more standard fodder. Likewise, Bluetooth, Draft-N wireless and Intel's GN40 chipset - offering GMA 4500M graphics and 720p video decoding - aren't anything exceptional.
Battery life is a claimed 5.9 hours from a 6-cell, 5200mAh unit, although whether that's obtainable in real-life is possible.
