Older Asus Eee PC Batteries Are Incompatible With 900A

From Gizmodo -

A word of caution to Asus Eee PC owners who may want to use their older batteries with the Atom-based Asus Eee PC 900A. It uses a different and cheaper (4400mAh) connector than the previous models 701 and 900. Meaning, older batteries will not work with it.

Looking at the brighter side, the 900A's 8GB SSD uses a single pci-e card, not a split one; and the SLF flash should give you speeds comparable to the 900/901 4GB SSD.
