Difference between 2G Surf and 4G Models

For those who can't decide which model to buy, below is a list of the differences between the 2G Surf and the 4G -

The 2G Surf does not have the following which the 4G has:

Memory door - entire bottom of unit is a solid piece of plastic.
2nd mini pci
Modem header
Camera socket is empty

Other limitations:

Cannot upgrade memory, RAM chips are directly integrated onto the motherboard.

Other downgrades:

800Mhz Celeron 571Mhz with no cache
4cell 4400 battery

Other Differences:

Slightly different arrangement of power pins near the ethernet switch chip.

Depending on your intended usage, the extra internal space and cheaper price might actually make the Eee PC 2G Surf an attractive buy. :)
