MSI X-Slim laptops: Micro-Star International is beefing-up its X-Slim laptop line with new X340 machines that feature a more powerful processor than previous models. The X340 Pro laptop is based on Intel's new 1.4GHz ultra-low voltage Core 2 Solo processor, which should make it more suited to multimedia applications than its predecessor. A second new laptop, the X340, has a 1.3GHz chip. Both have a 13-inch wide-screen display with 1,366 pixel by 768 pixel (WXGA) resolution. Other features include HDMI and monitor ports, Ethernet, 802.11b/g/n Wi-Fi, Bluetooth and optional WiMax modules. The X-Slim laptops typically turn heads because they're about the same size and thickness as Apple's MacBook Air but run Windows. Even with the upgrade, the Apple machines still pack more powerful processors. Launch dates for the X340 have not yet been fixed. It is expected to retail for between US$700 and $1,000.
