The MSI X-Slim notebooks debuted at the CeBit 2009 last March. Today MSI detailed the X-Slim X320 and X340 for the United States.

The MSI X-Slim series notebooks weigh just 2.8 lbs, but come loaded with the most storage space and the largest battery (4-Cell) in their class.
The X340 is among the first notebooks to feature the new Intel CULV CPU, which uses 1/6th the power of a regular mobile CPU, significantly increasing performance-per-watt over previous single-core processors.

The notebook also features a HD 16:9 Theater Display LCD with 1366x768 resolution and a HDMI port for 1080P playback for under $1,000.
Starting at $700, MSI chose to outfit the X320 with the new Intel Atom Z530 1.6GHz processor and an optional 3G/WiMAX solution for unmatched connectivity.

The specifications for the X340 and X320 are quite different. It will be interesting to see reviews that compare the X320 and the X340.

Features of the MSI X340 include Intel ULV SU3500 CPU, 13.4 inch screen, up to 4GB RAM, 320GB HDD, Intel GS45 chipset, Intel GMA45000MHD GPU and Wi-Fi.

The Features of the MSI X320 include Intel Atom Z530 at 1.6Ghz, 13.4 inch screen, Intel US15W chipset, Intel GMA GPU, up to 2GB RAM, 250GB HDD and Wifi.
Both X-Slim notebooks will start shipping in May.
