The MSI Wind PC will come in both Windows XP Home and Linux versions and will cost around £300 – a similar price to the Asus Eee PC.
"With Wind we struck the optimal balance of price, performance and convenience", said Daniel Wang, general manager of MSI US. "We designed the Wind to offer mobile consumers all the features of bulkier more expensive notebooks, but with a sleeker lightweight footprint and an affordable sub $500 price point."
The Wind is actually a sort of acronym, taking its name from Wi-Fi, Network and Device. This rather laboured not-quite-acronym is unlikely to deter potential customers, however.
The MSI Wind will run on an Intel 945GMS Atom processor and a minimum of 512MB of 667MHz DDRRAM for up to five and a half hours on a six-cell battery setup. The three-cell battery in the Linux version will last for around two-and-a-half hours between charges.
Both models will have 10in LCD screens and full Qwerty keyboards. MSI says the keyboard will be 20 percent smaller than a standard laptop keyboard, which should mean it's large enough for comfortable and sustained spells of typing.
An 80GB hard drive and a 1.3Mp webcam are also common to both models, while the Windows XP version will have a more generous 1GB DDR RAM compared with the Linux Wind's 512MB.
The MSI Wind PC will have 802.11g Wi-Fi and the Windows XP version will also come with Bluetooth connectivity. A 4-in-1 card reader and 3 USB ports will be standard on the two machines.
The MSI Wind will go onsale from early June via msimobile.com.
