We decided to pop open the Cr-48 to see how it compares to the new Series 5.

The similarities include:

Separate motherboard & I/O board layout with mini-PCIe cards for WWAN, Wi-Fi, and flash memory.

Intel NM10 graphics cards are used in both machines.

The major differences are:

The Cr-48 has removable/upgradeable RAM, while the Series 5's RAM is soldered to the motherboard.

The Cr-48's battery is accessible from the outside of the machine, while the Series 5 must be cracked open to swap out the battery.

The Series 5's Atom N570 processor sports dual cores with a total of 512K more L2 cache than the Cr-48's single core Atom N455.
