Have you ordered the C64x?

160 GB hard drive, where do you find them that small?  2 GB ram in 2011?  Underwhelming to say the least.

Sorry, I checked again and you're right, the info is spread all over the place.
So, for your $595.

C64x Basic:
Intel® Atom D525 1.80GHz (fastest current Atom)
Mini ITX motherboard based on the Intel NM10 chipset with Nvidia Ion graphics (DX10 compatible)
Multi format card reader
2GB DDR2 memory
160GB hard drive
No DVD drive*
No wifi*
* included in the $695 C64x Standard (which includes a larger 250GB hard drive)

I wasn't aware OS4 had been ported to it.

2GB of RAM should be plenty to run any C64 application you throw at it.
