MSI trots out CX640, CR640 laptops with USB 3.0, Core i3 CPUs

MSI has a pair of new “mainstream” notebooks available for the taking starting today. Both the CX640 and CR640 laptops share a few similarities, including fairly affordable price tags.
Running on Intel Core i3-2310M processors, both notebooks sport 15.6-inch displays, 4GB of RAM, 500GB hard drives and a pair of USB 3.0 ports each. Those hard drives are supposed to be extra-protected from drops and shocks as the disk is in the middle of the chassis and housed inside a “unique” casing.
MSI also promises that these C Series notebooks will boot up “two times faster than standard notebooks.” Presumably, MSI means notebooks in the same class. With these specs, the CX640 and CR640 are nice, but not that far off from standard.
The major difference between these two portable machines is that the silvery CX640 hosts NVIDIA® GeForce GT 520M graphics with Optimus technology, and the black CR640 uses Intel HD 3000 graphics.
The CR640 runs for a bit cheaper at $629.99, while the CX640 costs $679.99.
