Samsung launched a lightweight laptop at the IFA electronics show in Berlin that appeared to be squarely targeted at Apple's Macbook Air.

The Samsung X360 has a 13.3-inch screen, just like the Macbook Air, and was revealed at a news conference entitled "Lighter than Air." And according to specifications it just about meets that claim. The X360 weighs 1.27 kilograms, which is only 90 grams (the weight of a mobile phone) lighter than the Apple machine.

It doesn't appear as thin as Apple's machine, although Samsung didn't provide external measurements. However, given the competitive nature of the X360 launch, the specifications would likely have been disclosed had they been a level beyond the Macbook Air.

But that's about where the comparisons should end because Apple's machine is based on its own Mac OS and the X360 will run Windows Vista. There are few buyers who would likely consider them both and go on to make a buying decision based on physical specifications.

The X360 is based on Intel's Core 2 Duo processor and there's a 128GB SSD (solid-state drive). SSDs are based on flash memory and should allow PCs to start and shutdown faster than laptops with hard-disk drives. The screen offers 1,280 pixels by 800 pixels resolution. Other features include a built-in 1.3-megapixel webcam, Bluetooth 2.0, 802.11n wireless LAN, 3 USB ports, HDMI (high definition multimedia interface) connector and Express Card slot.

Battery life on the X360 is between 6 hours and 10 hours depending on usage, according to Samsung.

It will be launched in September in the UK, France, Germany, Spain, Italy, Russia and Hong Kong. Pricing and launch details for other markets were not announced.
