Although the full specifications don't hold any revelations as such, one interesting bit of information is that the X320 will be available with a 3G modem option, although we're pretty sure this will only be available as a tie-in with a mobile data contract.

The X320 will come with an Atom Z530 processors clocked at 1.6GHz and it's paired with the US15W chipset with Intel GMA500 graphics. Unlike the Dell Mini 10, it seems like the X320 will have upgradeable memory, as MSI lists 2GB as an option. It will also feature a 250GB 2.5-inch SATA hard drive, Gigabit Ethernet, 802.11b/g/n WiFi, Bluetooth 2.0 with EDR, an SD/MMC memory card reader, a 1.3 Megapixel webcam, three USB 2.0 ports and a D-sub connector.

Depending on price, the X340 looks like a much more appealing product, despite the fact that it won't be available with a 3G modem option. The X340 will have an Intel ULV SU3500 Core 2 Solo processor clocked at 1.3GHz with 3MB L2 cache, the GS45 chipset with Intel GMA4500MHD graphics, up to 4GB of DDR2 800MHz memory, a 320GB SATA hard drive and HDMI on top of the spec's of the X320.

As previously known, both models will have a 13.4-inch screen with a resolution of 1,366x768. With the standard 4-cell battery, both models will weigh in at about 1.3kg. An 8-cell battery will be available as an option. Finally both models will be available in white, black and silver.

In related news MSI also announced its Wind U123 netbook which apart from the usual netbook specs will have an Atom N280 processor and the option of an internal TV-tuner. It will also be available with two different WiFi configurations and it has a 6-cell battery as standard.

All three models should hit retail in May.
