Eee 900-905

Did Asus jump the gun on the release of the 9"Eee PC? It hasn't been out that long yet and there have alread been several updates to it. Because they wanted to get the system out, they missed the Intel Atom processor by a few days. They had to release an updated system immediately called the Eee PC 901. Now they're going to release 3 more... the 903, 904 and 905. I'm not sure what the differences are between these 3, but all 3 are using the Eee PC 1000's case. They just have a 9" screen and full sized keyboard. It doesn't really make sense to me. If someone wants the larger keyboard, why would they not just buy the 1000? The 9" screen in a 10" laptop makes as much sense as a 7" screen in 9" laptop.
