Scott of ScottSoapbox.com ordered a 12000mAh battery for his Eee PC. The battery is, well, humongous, heavy, and it’s full of juice.
Scott’s Eee PC’s weight went up from 3.2 pounds to 3.75 pounds, which is pretty heavy for a netbook. But the battery should also be able to last from 8 to 10 hours.
The increased typing incline is too much when the netbook is used on a table. This is largely a personal preference but for me: while I can type with speed and accuracy at that tilt, I find it uncomfortable. And wrist discomfort doesn’t jive well with “all day computing”. However, I tend to do most of my typing with my wireless keyboard/notebook/netbook in my lap. Used this way the battery does not create an uncomfortable position as the battery (mostly) fits between my legs.
However, he does not recommend using this battery at this time.
