The pricing seems to be gradually getting lower and lower for the Eee PC lineup and the latest model to hit that magical sub-$300 price point is the Eee PC 900A. For those (myself included) that have become confused as to just what each Eee PC model offers, this $299.99 Eee PC features an 8.9-inch display, 1GB of RAM, a 4GB SSD and a 1.6GHz Intel Atom processor. This model is also running Linux as opposed to Windows XP.
The product listing does not mention a battery size, originally the 900A shipped with a 4-cell battery, but with the lower pricing I would not be surprised to see this shipping with a smaller 3-cell battery.
Otherwise, it seems like this is a great deal. Sure, the 4GB of onboard storage is limiting, but, thanks to the low pricing of SD cards and the built-in card reader that issue can easily be addressed. I am slightly cheap myself, so I have a hard time really calling a $299 price tag an impulse buy, but all things considered, that is pretty affordable for a full featured laptop and certainly a nicer deal than what we were seeing this time last year.
