We already know that MSI will be rolling out the X-Slim X420 notebook, and they will accompany that release with the 15.6″ X-Slim X620 that will also sport an Intel Core 2 Duo ULV processor and an ATI Mobility Radeon HD 5430 1GB graphics card, although this model comes with 4GB RAM which is accompanied by up to 640GB of hard drive storage, an 8-cell battery and a DVD burner. Tipping the scales at 5.3 pounds, it comes with a body that incorporates a mineral grain pattern. As with the X420, there is also no mention of its pricing and availability, so we’ll just have to wait and see. [MSI]
